A valve is a device that directs or regulates flow by opening, closing, or partially blocking a passage. If you want to become a plumbing expert, you also need to know about industrial valves and fittings. Without valves, there is no way to control the flow of pipes. Below Utmost flow control technology Co., Ltd will discuss some valve types and their applications with you.
1. Gate valve
Gate valve is the most common form of valve in the industry, the gate is lifted and the fluid in the pipeline begins to flow. Gate valves are designed to be fully open or closed; they are often used as shut-off valves to isolate piping systems. When the gate valve is open, there is no blockage in the flow path and little or no friction loss. Gate valves are used when linear fluid flow is required and minimal restriction is required. Gate valves are usually controlled by handwheels, pneumatic diaphragms, electric motors or piston mechanisms.
2. Globe valve
The globe valve is used to control the flow in the pipeline. Unlike the gate valve's "full-on or full-off" function, the globe valve is adjusted by the position of the movable disc (or plug) relative to the fixed ring seat. The ports of the shut-off valve can be straight or angled. This type of angled feed valve is typically used with corrosive or viscous fluids that tend to solidify.
3. Needle valve
A needle valve is essentially a shut-off valve used to control flow very finely. Needle-type industrial valves contain an elongated tapered plug that regulates flow with high precision.
4. Butterfly valve
Butterfly valves are designed to regulate flow, but have limited control capabilities. This is a relatively simple industrial valve that can be operated by simply rotating the handle 90 degrees.
5. Check valve valve
A check valve, also known as an NRV, allows fluid to flow in only one direction, the purpose of a check valve is to prevent backflow. There are many kinds of "stops" that prevent backflow in a check valve. Ball check valves and piston check valves operate with minimal pressure. The return force is not enough to bring the ball or piston back in the opposite direction. Flow in a rotary check valve pushes a hinged flap that opens only in one direction to ensure fluid does not flow backwards.
6. Safety valve
A safety valve, also known as a safety valve, is an industrial valve and fitting that is installed to limit the pressure in a system. This type of angled supply valve is strictly used to prevent overpressure that can cause damage to the system.
7. Ball valve
The ball valve has a very good closing function. A simple quarter turn of 90 degrees fully opens or closes the valve. This feature minimizes valve operating time and reduces the potential for leaks due to gasket wear.
