Check Valve

A check valve is also known as clack valve, non-return valve or one-way valve. It is a mechanical device which normally allows liquid or gas fluids to flow through it in only one direction.

The check valve is a two-port valve, meaning it has two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications.

Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and/or inexpensive. They work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.
As a China check valve manufacturer, Hengnuo Valve also produces ball valve, forged steel valve, gate valve, butterfly valve, flange, and more.
