A valve is a device that is used to regulate pressure and is responsible for stopping and connecting the flow of fluids such as gas and liquids. Therefore, the valve is one of the widely used equipment that is used in various industries. Today, all kinds of industrial oil and gas valves are sold in the market, each of which has its own use.
What are the components of industrial valves?
Before we examine the types of valves, you must first familiarize yourself with their components in order to better understand how each one works. Types of industrial valves, apart from their type and application, include the following components:
- Body: The valve body (or shell) is the outer shell of the valve through which the fluid flows and other parts of the valve are placed in it. Bonnet: This part is placed on the body of the valve and bears the most pressure after the body. However, some valves do not need a bonnet.
- Trim: The internal components of the valve, which includes the disc, seat and stem, are called trim. All movements of the valve, from initial movement to flow control, are caused by the presence of trim.
- Disc: This part is used to block or control the fluid flow.
- Seat: This is the inner part or part of the body. It is milk. Also, the seat is where the valve is placed when the valve is closed.
- Stem: The stem is responsible for performing the necessary movement on the disc. It also controls the closing of the valve and the position of the disk.
All kinds of industrial valves
Gate valves are designed to act as isolation valves. These valves help control the flow of liquid in pipes. These valves are attached to pipelines to start or stop the flow of water or any other liquid. Gate valves are used for various purposes and are usually seen in homes and commercial centers. To make these valves, various materials such as stainless steel, cast iron, alloy steel and forged steel are used.
2. Ball valve
The distinguishing feature of a ball valve is its hollow ball-shaped disc that acts to stop or start the flow. The disk part of the ball has made it possible to create a milk with fast performance. Because it only needs a quarter turn to open or close. 3. Butterfly valves
Another thing that is included among all types of fittings and industrial valves is the butterfly valve. These valves are designed to regulate flow, but have limited control capabilities. Butterfly valves are easy to operate with a 90 degree rotation of the handle. This valve consists of a metal disk in the valve body, which is placed perpendicular to the flow in the closed state. Adjusting the liquid flow can be allowed through intermediate turns.
4. Check valve or one-way valve
A check valve relies on internal pressure to open and close, rather than external pressure. Also known as non-return valve. Preventing backflow is the main function of a check valve.
This valve got its name from the needle-like shape of its disk. The needle valve provides greater precision and control in smaller piping systems. The performance of this type of valve is similar to the ball valve. In smaller piping systems, needle valves give you more control over flow. In flows with low pressure, needle valves show a very good performance.
6. Strainer valve
Strainer valve is another type of industrial valve that can be defined as a piece connected to a pipe that is used to filter, filter or separate different materials from the flow. Strainer valves filter pipeline debris such as scale, rust, joint compound and weld metal from pipelines. Therefore, they protect the equipment and processes against the harmful effects of these substances, thereby reducing the time of failure and repair of parts.
7. Ball valve
Ball valve is another widely used type of industrial valve. The distinctive feature of ball valves is that they have a channel in the shape of the English letter s. The hemispherical disk is responsible for opening and closing the flow of liquid or gas in these valves. By raising and lowering it, you can control the flow of liquid or gas. The strength of this type of valve is that it allows you to better control the pressure. Also, they close better than other valves and do not suffer from wear and tear due to continuous opening and closing. Of course, ball valves can withstand a higher flow of liquids or gases.
8. Samavari valve
These valves are one of the types of industrial valves that have an opening and closing mechanism similar to ball valves. These lions are called Samavari lions because of the conical shape at their ends.
