Advantages And Disadvantages Of Ball Valves
Ball Valve plays a vital role in daily life as they are used day to day basis, say it from bicycles or automobiles, jet airplanes or any industry. There are different sizes and shapes of valves and each has various dimensions, functions and applications to it.The industry has numerous use of the Ball valves and in order to ensure that these valves remains functional during the operation, it is safe to maintain it before it gets corroded away. Regular cleaning and lubrication to ensure the smooth functionality is key to their life span.
These valves are categorized into five general bodies which includes three piece bodies, two piece bodies ,single body top entry, a split body and welded. The following qualities make them an excellent choice for controlling various applications and sometimes they are preferred over any other valves which has less control in the throttling applications.Advantages Of Ball Valves
They provide leak-proof service,
Open and close quickly,
Compared to gate valves, they have very small dimensions,
Compared to gate valves, they are lighter,
The multi designed flexibility does not exist in the Gate or Globe valve, and hence it lowers the amount of valves needed,
These valves are manufactured in different sizes and shapes providing flexibility in selection,
The high quality valves provide safe service under high temperature and high pressure conditions, and
Compared to other valves, they are controlled with less force.
The main disadvantages of these valves are as follows:
The position of the valve handle is rotated,
Could not be used for throttling, and
These valves with drive mechanism should be installed upright.
At Boson Engineers, we have a wide range of valves that are manufactured according to customers specific needs which includes the ball valves that are designed using the latest technology and is suitable for crucial operations. Our valves are easily accessible and can be maintained easily with low maintenance cost, high quality and are resistant to corrosion.
Strainer Valve: a basic guide to know it better
Strainer valve can be defined as a pipe fitting through which liquid is passed for purification, filtering or separation from solid matter; anything used to strain a liquid; any device functioning as a sieve or filter used to prevent solid bodies from mixing in a liquid stream or flow line. Strainers arrest pipeline debris such as scale, rust, jointing compound and weld metal in pipelines, protecting equipment and processes from their harmful effects, thus reducing downtime and maintenance.A Y Strainer valve takes its name from its configuration and is most commonly used in pressurized lines, gas or liquid. They can also be used in suction or vacuum conditions. Y-Strainers are intended for applications where small amounts of solid particulate are expected and where clean-out will be infrequent. If solids are flushed easily from the screen, and fluid can be exhausted to atmosphere, a blow-down valve on the drain port will allow clean-out without removal of the screen and without interrupting the process flow.
A Y-Strainer has the advantage of being installed in either a horizontal or vertical position. Obviously, in both cases, the screening element must be on the down side of the strainer body so that the entrapped material can be properly collected in it.
In horizontal steam or gas piping, Y type strainer should be installed in such a manner so that the pocket is in the horizontal plane. This stops water from collecting in the pocket which can cause erosion and affect heat transfer processes.
In liquid systems, the pocket should point vertically downwards. This ensures that the removed debris is not drawn back into the upstream pipework during low flow conditions.
Although it is recommended to install strainers in horizontal lines, this is not always possible, and they can be installed in vertical pipelines if the flow is downwards, in which case the debris is naturally directed into the pocket.
What is Gate Valve?
A gate valve can be defined as a type of valve that used a gate or wedge type disk and the disk moves perpendicular to flow to start or stop the fluid flow in piping.A gate valve is the most common type of valve used in any process plant. It is a linear motion valve used to start or stop fluid flow. In service, these valves are either in a fully open or fully closed position.
When the gate valve is fully open, the disk of a gate valve is completely removed from the flow. Therefore virtually no resistance to flow. Due to this very little pressure drops when fluid passes through a gate valve.
To achieve proper sealing, when the valve is fully closed, 360° surface contact is required between disk and seats.
Gate valves should not be used for regulation or throttling of flow because accurate control is not possible. The high velocity of the flow in the partially open valve may cause erosion of the disc and seating surfaces and also creates vibration and noise.
Globe Valve — Introduction, Advantage, Disadvantage and Application.
A Globe valves is a linear motion valve and are primarily designed to stop, start and regulate flow. The disk of a Globe valve can be totally removed from the flow path or it can completely close the flow path.Conventional Globe valves may be used for isolation and throttling services. Although these valves exhibit slightly higher pressure drops than straight through valves (e.g., gate, plug, ball, etc.), they may be used where the pressure drop through the valve is not a controlling factor.
The globe valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop. The globe valve is an excellent valve to use in high pressure operation of steam. Our globe valves are factory-made with quality material for long term use.
Advantages and disadvantages of Globe valves
ADVANTAGES:
Good shutoff capability
Moderate to good throttling capability
Shorter stroke (compared to a gate valve)
Available in tee, wye, and angle patterns, each offering unique capabilities
Easy to machine or resurface the seats
With disc not attached to the stem, valve can be used as a stop-check valve
DISADVANTAGES:
Higher pressure drop (compared to a gate valve)
Requires greater force or a larger actuator to seat the valve (with pressure under the seat)
Throttling flow under the seat and shutoff flow over the seat
The following are some of the typical applications of Globe valves:
Cooling water systems where flow needs to be regulated
Fuel oil system where flow is regulated and leaktightness is of importance
High-point vents and low-point drains when leaktightness and safety are major considerations
Feedwater, chemical feed, condenser air extraction, and extraction drain systems
Boiler vents and drains, main steam vents and drains, and heater drains
Turbine seals and drains
Can you recycle wrapping paper?
We throw away an estimated 227,000 miles of wrapping paper each year at Christmas in the UK, according to waste management company BIFFA.That’s enough to wrap around the Earth… more than eight times.
But it brands itself as paper – so surely it all just gets recycled?
The short answer? Not always.
And that’s because gift wrap often contains much more than simply paper.
“It’s a nightmare for paper mills this time of year,” confesses Simon Ellin, the chief executive of the Recycling Association – a trade body that represents around 90 different paper merchants, waste management companies and other businesses involved in recycling paper.
That’s because while they’re presented with mountains of wrapping paper, they cannot work with all of it.
“Not all wrapping paper is paper,” Simon points out. Some is plastic-based.
Then there’s the issue of paper that’s laminated with plastic not to mention gift tags or paper that contains foil or glitter, none of which can be recycled.
But once you’ve removed these items you can recycle a good deal of what you’ve wrapped your presents in, just as long as it’s pure paper.
How do you check? Try to scrunch up the paper into a ball. If it scrunches, and stays scrunched, it can probably be recycled.
And if you’ve bought recycled wrapping paper in the first place, it can probably be recycled again.
So you’ve got recyclable wrapping paper – what do you do with it?
Even if your paper is recyclable – not all councils will take it.
Some will let you put it into the recycling collection. Others insist you bring it along to a recycling centre.
You’ll need to check with your local authority. To find out which one takes your rubbish, click here for England and Northern Ireland, here for Wales and here for Scotland.
But could we do better than just recycling?
Well, we could make sure that the paper we buy in the first place is made from sustainable sources. This means that it hasn’t resulted in deforestation or environmental damage.
You can look out for FSC-certified wrapping paper and other Christmas items such as cards and crackers.
Even better would be to not throw the paper away in the first place – but reuse it.
The Environment Agency has suggested that you make your own wrapping paper, as this encourages reuse: “How about getting creative using potato stamps to decorate parcel paper and adding a sprig of holly for that Christmas feel.”
Or you could try to avoid wrapping paper altogether. Furoshiki are traditional cloths from Japan which are used to wrap presents instead of paper. The cloth can then be reused in future years or even given as a gift itself.
Candy Packaging: A Trick or a Treat?
The holidays are often a time for giving into guilty pleasures, and for many of us that means indulging in one too many treats. As we enter a different kind of holiday season with a heightened focus on food safety amid a pandemic, there’s a greater emphasis on the need for keeping the food protected properly, including the wrapping on your favorite sweets and candies. As a result, a unique dilemma has emerged – what do we do with all the packaging, especially since much of it can’t be easily recycled through traditional methods?The “Scare”: The Packaging We Need is Difficult to Recycle
Candy wrappers are primarily designed to keep products fresh and safe for consumption, and in the case of softer treats like chocolate, help maintain form and avoid the messes that might result from melting. Many of these wrappers are made from innovative solutions that combine different materials like aluminum, paper and plastic. This mixture of materials is highly effective at maintaining quality, and keeping packaging weight to a minimum, but it presents a real recycling challenge.
The other aspect of the challenge here in the U.S. is accessibility, while in other parts of the world they’re a few steps ahead. In Australia, for example, soft plastics from many chocolate and lollipop wrappers are recyclable through the Red Cycle collection bins available at most supermarkets. The wrappers are recycled and then used to make products like benches and fences.
The “Trick”: Thinking Outside the “Zero Waste” Box
Traditionally recycling would be as easy as dropping the wrappers in your curbside cart, but because candy wrapping is made with mixed materials and can’t usually be sorted that’s not possible. A few local markets offer special solutions, so if you have access to one of those count yourself as lucky, but most consumers in the U.S. can’t utilize their curbside collection program. There are, however, a few alternative solutions that build on the power of many by recycling in bulk.
Enter waste collection boxes, a relatively new approach to recycling your wrappers and the only widely available solution in the U.S. market. Variations like TerraCycle’s Zero Waste Box and Rubicon’s Trick or Trash box allow for recycling of any size or brand of candy and snack wrapper.
The “Treat”: An Investment For Your Community and Beyond
Purchasing just one box can bring together an entire neighborhood. It’s much larger than any one family would need, so use it as a way to bring your neighbors together. By having a few houses chip in, the effort not only becomes more economical, it helps advance the next evolution of recycling.
This year, Rubicon distributed at least one Trick or Trash box to schools and small businesses in every U.S. state. The more we embrace innovations like these, the more accessible they become, and the fewer materials go to waste.
I am confident that in the not too distant future our favorite candies will be wrapped in materials that are 100% recyclable, but until then, we shouldn’t be “scared” away from the best options of today.
Everything you need to know about candy packaging
The phrase ‘looks aren’t everything’ almost certainly does not apply to new products that you want to introduce to the market. After all, there is no doubt; the more attractive the candy boxes and wraps are, the more people will be interested in trying it out.
And although it might be a struggle to keep up with and stand out amongst the latest trends in candy packaging, this step is crucial to create an interesting product your customers will love. So you might be wondering, is it really that important for me to create innovative packaging?
The truth is, you do. The reasoning for this is simple – imagine yourself standing in an aisle in your local grocery store, staring at the hundreds of different candies, each with their own candy packaging.
That is what most of your customers will see when they encounter your product, which is why you need to make it stand out.
Candy Packaging trends
Before you can be innovative, you need to understand what the trends in packaging design are – with this as background knowledge, you can apply your twists to your product in order to truly make it your own.
Convenience Packaging
Put simply, these are the kind of candy boxes and supplies that are convenient to open, use, and discard of. The data, as claimed by other candy brands is consistent: your customers won’t just love candy packaging that is convenient – they may go out of the way and actually pay more for it.
You might have seen this elsewhere when it comes to packaging – the use of clear plastic bags for candy is an obvious choice, and it is clearly one that appeals to the customers as well. These plastic pouches are just so easy to eat from because of their ability to be resealed.
The journey towards paper packaging for chocolate
How do you ensure both barrier functionality and recyclability?This is indeed a challenge we are facing. We are using a special functional barrier paper. When we started the development process two years ago, there was no functional barrier paper available, but development has moved fast since then. The paper we used is coated with a water-based barrier material that is fit for recycling in the paper recycling stream. Of course, it would have been easy to use lamination instead, as this makes product protection easier. But even a thin layer of laminate makes recycling difficult, which is a key feature for us to give the material a second life. We are already using a lot of recycled paper materials for our displays, trade units etc. What we have now is not perfect yet, but this is a step-by-step process and a development journey. In 2021 we will launch a paper-based pouch, and we will integrate the learnings from that into the development process. We do not know if and how and when we will have 100% of paper-based packaging for 100% of our products, but it is a development journey.
Do you have any life cycle analysis data available yet comparing the paper packaging and the standard Ritter Sport packaging?
For us it is not so important to have answers as soon as possible, but to have the right answer. It’s about more than an LCA, it’s about the ecological footprint, CO2, water, energy consumption, energy sources, and what happens after consumption. We want to understand all pieces of the jigsaw and adapt it piece by piece. I would like to underline that I don’t want to engage in plastic bashing. Even though we have been talking a lot about paper, our plastic packaging material does a great job too – it is recyclable, albeit more in theory than in practice, and weighs just 1.5 grams. Our overall intention is to look at the future and to solve issues, one of which is recyclability, which is not always given especially for flexible packaging. In Germany, we have a good collection and recycling infrastructure for plastic, but internationally, there are better better collection and recycling systems in place for paper than there are for plastics, so we believe in paper and also want to understand plastic better. Packaging is an integral part of the overall Ritter sustainability strategy. We often talk about raw materials such as cocoa in a sustainability context, but consumer see the packaging just as much as they see the chocolate, so it is just as important as the ingredients are.
Why you shouldn’t wrap your food in aluminium foil before cooking it
If you’re baking fish, roasting vegetables or preparing a piece of meat for dinner tonight, chances are that you’ll wrap your food in aluminium foil. What you may not realise is that some of the foil will leach into your meal – and this could be bad for your health.Research that I conducted with a group of colleagues has explored the use of aluminium for cooking and preparing food. Aluminium doesn’t just appear in foil: it is the most popular cookware material used by people in developing countries. Pots and pans are lined with it and it is found in some kitchen utensils like large serving spoons. Copper used to fulfil this role, but over time it’s been replaced by aluminium because it is cheaper to mass produce and easier to clean.
But while cooking your food in aluminium pots or pans isn’t a bad thing, placing it in foil and putting it in the oven is problematic. This is especially true with acidic or spicy food that’s prepared at high temperatures.
Aluminium and health
Human bodies can excrete small amounts of aluminium very efficiently. This means that minimal exposure to aluminium is not a problem: the World Health Organisation has established a safe daily intake of 40mg per kilogram of body weight per day. So for a person who weighs 60kg the allowable intake would be 2400 mg.
But most people are exposed to and ingest far more than this suggested safe daily intake. Aluminium is present in corn, yellow cheese, salt, herbs, spices and tea. It’s used in cooking utensils, as described above, as well as in pharmacological agents like antacids and antiperspirants. Aluminium sulfate, which is derived from aluminium, is used as a coagulant during the purification process of drinking water.
Scientists are exploring whether over-exposure to aluminium may be posing threats to human health. For instance, high concentrations of aluminium have been detected in the brain tissue of patients with Alzheimer’s disease. Scientists have examined the community of old people with Alzheimer’s and concluded that it is a modern disease that’s developed from altered living conditions associated with society’s industrialisation. These conditions may include high levels of aluminium in daily life.
Aluminium poses other health risks, too. Studies have suggested that high aluminium intake may be harmful to some patients with bone diseases or renal impairment. It also reduces the growth rate of human brain cells.
