Professional Brass Valve Manufacturer in China

Nowadays, you can find several types of valves available in the market. As each valve is made up of different materials, it might be quite confusing to choose the best one. The brass valves are versatile and it has a wider range of properties than the bronze valves. You can find several types of valves for fitting purposes, which is used in varied industries. They include ball valve, gate valve, stop valve and bibcock.

Why Brass?

Brass is a malleable than bronze. It is primarily made from copper and zinc. Brass is widely used in different types of applications. Even though it has high levels of chlorine that can break down zinc content, it doesn’t oxide quickly. There are many properties of brass which has resulted in it being used as the choice of material in a different type of appliances. Easy to cast, easy to forge, heat extrude are one of those properties of brass, which makes it extremely versatile and hence making it extremely easy to work with.

Usage of brass valves:

Brass is versatile to use. As it possess different preferable properties, they are used many several applications. They are mainly preferred in households, through the usage in the commercial sector is also not uncommon. These are especially useful when hot water is used because the brass valve is more preferable when the household has hot water through its pipes.

Brass can withstand higher temperature. Hence, even at a higher temperature, these valves will perform with the same efficiencies. Due to the ability to withstand high temperature, brass valves are widely used when there is hot water in circulation. Along with beauty and ease to use, brass is one of the most widely used alloys. While gathering the complete list of applications where brass is used, we can get an idea on the range of industries and the categories of products in which brass is found.

Benefits of brass valve:

There are different benefits of the brass valve for which it has been widely used in various systems. For example:

• Versality: Brass as a material can be used for so many purposes and hence, the brass valves also inherit that property. For example, the brass could withstand even high temperature which makes it useful in manufacturing valves for pipes through which hot water will flow. If one needs exact fitting of the valves or any other type of appliances in a system, then the brass serves pretty well as making it a perfect fit.

If you are on a project where you have strict specifications about the size or shape of the components that you can use, then brass can come to the rescue. Brass is stronger than plastic. The main advantage of brass valves are the reduced levels of lead present in the metal. This marks it harmless for drinking water in most of the cases. Another use for brass valves is as of the shut-off valves that are used in natural gas lines.

• Durability: Another advantage of the brass valve is its durability. Brass as a material is very durable in nature and hence, when you are using a brass valve, you are assured that these valves will last for a long period of time and you won’t need to replace them any time soon. When a plumbing system needs a longer life, it is better if you will choose brass valves, with their durable nature, the brass valve comes as the first choice of candidates when it comes to building a system that will be highly durable in nature. These valves will remain in good condition even after years without any cracks or any other types of anomalies. That’s why, due to the durable nature, brass valves are widely used in the various system so that the system will work a longer period of time without any need of repair. You can avail brass fittings in different shapes, sizes and finishes. Therefore, if you have any plumbing job to be done, it is essential to use brass fittings as it apt for very specific sizes. For all those external fittings, there are variety of finishes available in brass.

• Brass can withstand high temperature: Brass can withstand high temperature. This is why it is a first-choice material for the pipe systems where the temperature play a major part. Due to its conductivity, the heat is also spread across a wider area and hence, brass makes it easy to conduct heat across the system with its property. Due to the fact that brass can withstand high temperature, they are widely used in a variety of applications. It could even be survived in a firehouse, as it has ductile properties and can withstand high temperature.

Resistance to corrosion: Brass is one of those materials which are highly resistant to corrosion. Corrosion can cause rust which can lead to wear and tear effect to the system due to which, the whole system could fail to perform as expected. But as brass is highly resistant to corrosion, it makes it a perfect choice for all those areas where the corrosion is highly expected and thus, the wear and tear effect along with the rust could completely be avoided. As brass is immune to corrosion, even the worst corrosive water can’t cause corrosion in brass.
Malleable: Brass is very malleable in nature and hence, it is easier to bend or shape different brass components than the components that are made from other material. This makes the work smooth as you can forge the brass to suit your need and perfect fitting. The cost also becomes lower.. Since, brass is more versatile than any other metal, it is widely used in several industries, for different purposes.

You can easily find brass fittings of different price range and quality. It is essential that you make purchases from a reputed dealer in order to get the best deal and good quality product. With loads of advantages and added beauty, brass always stands as the best choice, which can be used in any industry.

What is a valve? A valve is a device that regulates the flow of a liquid by opening or closing or partially obstructing the flow in its pathway. They are used in many appliances where unidirectional flow needs to be achieved and the flow from opposite direction could be prevented.

What is a gate valve?

The gate valve is a type of valve that is widely used in pipelines. A gate valve has a variety of functions when fitted in a pipeline but its main role is to connect and shut off the medium. The gate valve mechanism doesn’t have much effect on regulating the flow of the liquid, after it can completely get connected or shut off the medium. Due to its property, the gate valve has found many applications across a wide range of devices. Be it a pressure application, the gate valve could be used. Or it can also be used in an application where pressure and calibre are involved. That’s why it has a much wider range of applications than the other types of valves.

When are they used?

These valves are often used when there is a requirement of minimum pressure loss and the free bore is required. As it has been already mentioned above, the gate valve operates via connecting or shutting off the medium. When the gate valve is opened fully, the valve connects the medium and there is no obstruction in place. This, in turn, results in very less amount of pressure loss. The gate valves are used in a wide range of devices which are associated with pipelines supplying water, gas etc.

Types of gate valves:

Based on numerous aspects, one can choose gate valves from a variety of options. But all these can be divided into two main categories. One is parallel gate valves and the other one is wedge-shaped gate valves. These two has a different structure and thus comes with their own set of features.

• The parallel gate valves use a flat gate in between two parallel seats. The popular type of gate valve is also of the parallel mechanism which has a knife gate valve as well. The knife gate valve is designed with a sharp edge at the bottom of the gate

• In contrast to parallel gate valves, the wedge-shaped gate valves have two inclined seats whereas, in the case of parallel gate valves, the two seats are parallel in nature. The wedge-shaped gate valve is crafted with a slightly mismatched inclined gate to suit the purpose best.

Advantages of gate valves:

The advantages of gate valves multiply the usage of gate valves in the field of pipelines. They are used in water supply, gas supply etc. The gate valves are useful in connecting and shutting off the medium and this property of the gate valve gives them the advantage. Another aspect of the gate valve is, these valves are often used when there is a need to minimize pressure loss and the free bore is required. Here are the few of the advantages that the gate valves hold above others.

• As it has been already said, the resistance that is offered by the gate valve is very small. This minimum pressure loss property makes it a suitable candidate for the processess where there is a requirement of minimum loss of pressure. The loss of pressure is minimum in case of gate valve because the body of the valve is a straight one and no change of direction takes place in the valve. Had there been a change in the course of the medium, there would have been a loss of pressure as the change in course can lead to a loss of pressure. But in the case of gate valve, there is no such change in the course and this makes gate valves most fitting for the circumstances where there is a requirement of minimum loss of the amount of pressure.
• The gate valve works through the connecting and shutting of the medium. The performance of any valve depends on the sealing mechanism. A better sealing mechanism leads to a better performance of the valve. The sealing mechanism of the gate valve is much better than those of other valves and hence, the gate valve is widely used in different fields. The opening and closing mechanism of the gate valve is also more convenient in case of gate valve than the other types of valves.

• Due to the property of less amount of pressure loss and connecting and shutting off the medium, the gate valve is also used in various types of applications. For example, excluding steam, oil and another medium, it is also used in the flow of granular solid which has a large viscosity. The gate valve could also be used as venting valve and low vacuum system valve. Due to this wide range of properties for which, the gate valves are especially used in different types of circumstances and they are getting more and more roles in different fields.

Disadvantages of gate vales:

With all the advantages in place, the gate valve also has some disadvantages also. These disadvantages may include:

• The opening and closing time of the gate valve is too long and hence, in some cases where the valves do need to operate in a swift manner, the gate valves fails to serve that purpose. The prolonged opening and closing time also make it unsuitable for the flows where you need to connect and shut the medium off immediately.
• Though the sealing mechanism of the gate valve is much better than any other types of valves, due to being itself prone to scratch, over the time, the gate valve may lose its efficiency. There will be friction between the plate of the valve and the two-sealing surface and over the course of time, it will lead to wear and tear. Thus, the sealing mechanism will fail to work at optimal performance.

Despite certain major drawbacks, gate valves have a number of considerable advantages.

Various manufacturing industries, especially those connected with chemicals and fluid are well aware of the importance of valves. Valve is a device which is responsible for controlling, directing and regulating the flow of fluid. This regulation and control are done through the opening, closing or partly blocking the tubes through which the fluid flows. These valves perform different functions like starting and pausing fluid flow, changing the amount of fluid flowing through the tubes, controlling its direction, regulating pressure, etc. There are several types of valves being used in different industries. Let’s have a detailed look at them one by one.

1. Ball valve– These are the most widely used valves. They are designed in such a way that, they can either be fully opened or fully closed with any liquid container. They are produced by almost all valve, fitting, and bibcock manufacturers. The feature of these valves is, they can open and close quickly, are simple to operate, have fewer pressure drops and rarely have any problem in operation.

2. Globe valve- These are somehow similar to ball valves in operation. The disk of glove valve can either be removed completely to open the flow path or can be closed completely to block it. They are linear motion valves produced to start, pause and control the liquid flow. These valves have high-pressure drops but still can be used to throttle the flow.

3. Gate valve– Gate valves are also designed to either fully open or fully close the pathway of the fluid flow. They are made to start, stop the flow. They can also be used to ensure straight line flow the fluid or flow restriction. As the valve provides a tight seal when it is closed, it is used for the containers comprising various types of fluids including chemicals, reports a well-known valve manufacturer.

4. Needle valve- The use of needle valve is spread over in various types of industries. They are used to control and direct the flow of gases as well as liquids. They also serve the function of creating resistance to the flow. This helps in safeguarding delicate instruments from coming in contact with substances which are pressurized like various oils, gases and water. They are useful in circumstances when the gradual flow of fluid is required.

5. Plug valve- These valves are similar to gate valves. They allow unblocked flow and get opened with just 90 degrees of turn. They get operational with a small headroom. They don’t have screw threads and hence stem corrosion can happen in very low amount. As said by one of the most popular valves and bibcock suppliers, plug valves are mostly supplied with a plug which has elastomer coating. They get sealed very tightly. These valves are much larger than ball valves and are used mostly in wastewater treatment plants.

6. Butterfly valve- These valves are again similar to ball valves in operation and can open with just 45 degrees of turn. Their usage is mainly done to regulate larger flows of gases and liquids in various industries. However, they cannot be used in throttling for a longer period of time. They are more compact in nature when compared to the gate and ball valves.

7. Check valve– These valves can be called safety valves which are self-activated. They allow gases and liquids to flow in one direction. The reason behind using check valves is to resist the flow of fluids back to the system which can result in damage to equipment. They are mainly used for safeguarding liquid pumps and gas compressors so that there is no backflow as it can stop the pump or compressor from working. The main feature of these valves is they don’t need an external power supply for operation.

8. Swing check valve- These valves permit full, unhindered flow which starts closing as the pressure decreases. It gets completely closed when the flow is zero. They can be used in the systems where gate valves are used due to low-pressure drop.

Apart from these 8 types, there are other types like lift check valve, ball check valve, tilting disc, diaphragm, diaphragm check valve, backflow preventer, manifold valve, control valve, foot valve, safety and relief valve, etc. They are used in different industries for which their functioning and designs are suitable.
