lug type double-disc swing Check Valve

lug type double-disc swing 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.
