What Is a Check Valve?- Taizhou aike valve Co., Ltd

The Check Valve is a self-operating valve used in a wide variety of applications. Its purpose is to permit flow in one direction and prevent reverse flow. There are a number of factors that will affect the type of check valve you choose. These factors include cost, initial familiarity, required maintenance, and process media.

One of the most common problems with check valves is water hammer. This is a result of water pressure rising too quickly. It can also be caused by improper installation or maintenance. Even if it does not appear to be a problem at the moment, proper maintenance and installation will help prevent problems in the future.

Check valves are essential components of any fluid flow system. They require a certain amount of upstream pressure in order to open. Depending on the type and size of a valve, cracking pressure may be as low as 3 psi or as high as 350 psi. This pressure is also used to protect pumps and piping systems from damage.

Check valves are very important for water supply systems and are used to prevent backflow. If a backflow occurs, contaminated water may enter the sanitary system. These valves can also prevent contaminated water from entering the domestic water system.
