ANSI Check Valve

ANSI Check Valve

Check valve is a mechanical device, a valve, that normally only allows fluid to flow through it in one direction, also known as a non-return valve or one-way valve. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.

Check Valve are generally used in drip irrigation emitters and irrigation sprinklers. Check Valves are mechanical valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed. The mechanics of check valve operation are not complicated. Most check valves contain a ball that sits freely above the seat, which has only one through hole.

ANSI stands for American National Standards Institute. It is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide.

ANSI check valve describes that the check valve is according with ANSI standard, in other words, this check valve is high quality that could be accepted widely by world’s professional buyers and consumers.
