Classification and Benefits of Usage of Gate Valves!

Found mostly on the wider section of the pipe, gate valves are affixed to the pipelines to either start or stop the flow of water or any other kind of liquid. Both at residential and commercial places, gate valves are used for different purposes.

A gate valve is designed with an actuator and a gate. The actuator can be a handwheel, lever, or electric motor, with each making the controlling performance more convenient with the placed condition. And, the gate refers to a rectangular or circular piece of metal, which’s up and down, determines the passing or no passing of the flow.

Most commonly, gate valves are used to open or close the path of fluid from straight-line mediums. It may find applications in certain areas, such as for the purpose of irrigation and also in various chemical plants to control the flow of different kinds of fluids.

The Gate Valve Manufacturers offer different kinds of valves to their customers. In fact, considering the different needs, gate valve manufacturers design a wide range of proper specifications so as to meet various requirements. Otherwise, efficiency and performance cannot be ensured.

 

Gate Valves in Different Materials

There are several popular materials that are used for manufacturing gate valves. The ones made up of brass and bronze are quite common among the popular varieties. Various kinds of iron, including ductile iron, cast iron too, are used for manufacturing. And, steel, forged steel, stainless steel, cast carbon steel, and alloy steel are quality materials used for durable gate valves.

The Rising Stem Valve and the Non-rising Stem Valve!

There are many ways to classify gate valves, one of which is according to the behavior of the stem attached to these valves. The rising stem valve includes a threaded shaft that can be rotated using a handwheel. Some of the stems rise when the valve is opened while the stem descends when the gate valve is closed.

The non-rising stem valve is another kind of gate valve that neither ascends nor descends when the valves are opened and closed. The stem remains stationary at the same position. Such kinds of valves are commonly used in underground tunnels and places where there is little space.

Gate Valves with Different Bonnet Styles

Screw-in bonnet style is small in size and used for quite simple applications. On the contrary, high-pressure applications make use of large valves with bolted bonnets. For extremely high-pressure applications, the use of bolted bonnets offers a high level of safety. Gate Valve with a Union-style bonnet is another option that is used for applications where regular inspection is needed.

Wedge and Parallel Gate Valves

Different gate valves utilize different kinds of wedges and each valve is then distinguished accordingly.

  • The Flexible Wedge Valve

These valves include both one-piece and twin-piece to alter the angle in between the seats. These gate valves are quite flexible and can be found in different varieties. Commonly, a parallel side valve is used, that can expand and contract and is able to withstand the varying climatic conditions.

  • Solid Wedge Valve

This kind of valve can be used for all types of liquids. Being strong with simple construction, it is suitable for turbulent flow.

  • Split Wedge Valve

These wedges are ideal for corrosive liquids and non-condensing gas.

Benefits of Gate Valve:

Apart from performing the basic service to either stop or start the flow of water, there are certain advantages of using gate valves.

  • The gate valves can be used in both directions. The liquid can flow through the gate valve in any direction from both sides of the valve. This makes them quite efficient to be used for quickly controlling the flow of liquid.
  • Gate valves have incomparable sealing properties. They are known to completely shut down the flow of liquid. This ensures the durability of the pipe as the loss of pressure will be minimal with the use of gate valves.
  • Being relatively simple, it is easy to set up with a body structure that involves less complication and maintenance.

Butterfly Valves - Their Types, Uses, and Functions

Image
Butterfly valves are used to start, stop or regulate the flow of gases or liquids. The valve is named a "butterfly valve" because it looks like a butterfly. The valve may use manual or automatic actuators. Smaller-sized china valves have manual actuators, while the bigger ones use automatic actuators.  Butterfly Valves are used for : To regulate the flow. To isolate the flow. To prevent backflow. Butterfly valves are made of 4 main parts :  Body: It's the part that fits between the two pipes Seat: Either bonded to the body or locked down. Disk: It controls the flow of media through the valve. Stem: It connects the disk inside to the handle outside We can classify butterfly valves according to closure design, piping connection design, seat material, and actuation method.  According to the disc closure design, two variations exist, namely concentric butterfly valve and eccentric butterfly valve. According to piping connection design, we have lug type, wafer type, flanged,

Automatic Control Valves-Their Types and Function

Image
A valve is a mechanical device used to control the flow of fluids. There are two basic types of valves, an on-off valve that stops or allows the flow of fluid and a control valve that regulates the flow of fluids. Both types of valves are used in industrial and domestic applications. Valves open and close in response to variations in pressure, level, flow, or temperature in an industrial environment. Valves function by obstructing a passageway in piping by actuation of a ball, disc, or a plug. The actuating may be accomplished manually or may be automatic. Manual valves are manually operated valves . Manual actuation entails physical contact with a handwheel, lever, or gearbox operator. On the other hand, automated actuation uses air pressure, hydraulic pressure, or electricity. The working of these valves also depends on the flow of the fluid being controlled. Some actuators remotely indicate the position of the valve opening. Pneumatically operated valves are widely used for
