The primary function of a check valve is to prevent reverse flow, which can damage pumps and other mechanisms. When a check valve closes, it can cause water hammer, where the fluid in the system slams against the closed valve. This necessitates that check valves be resilient, durable, and...
The eccentric disc shaft combination with the disc seat guarantees a positive shut off returning media. Wafer check valves are becoming the preferred type of check valve for most applications, due to their compact design and relatively low cost. , The Single Disc Check Valve (Wafer Type Disc Ch...
WHAT'S COMMON TO ALL TYPES OF CHECK VALVES? There is a wide range of check valve types, and while each operates somewhat differently, all check valves share a few commonalities. Compared with other types of valves, check valves are relatively simple and inexpensive to purchase. ...
3. Butterfly valve: There is a rotating disc shaped valve disc inside the valve body, which controls the flow and flow of fluid by rotating the valve disc. 4. Check valve: used to prevent fluid backflow and prevent pipeline backflow. 5. Regulating valve: Control the flow of fluid by adj...

4. Check Valve In pipes, check valves stop backflow. Fluid pressure opens the valve. The genius of the check valve is that it closes if any fluid reverses the wrong direction. 5. Plug Valve As the name indicates, a plug valve stops the flow of fluids through a pipe by blocking them ...

This type of valve serves as the correcting element of a control loop. The control valve is typically operated automatically, but there are also some that can be operated by hand. There are several different types of control valves. Some of the most common include: ...
Valves are devices that control the flow of fluids (liquids, gases, vapors and more) by stopping, adjusting or allowing the passage of the fluid through its container. There are many types of valves available on the market and choosing which one to use i
