​SS316 Threaded End Spring Check Valve

Our Brand:
Description:
Spring check valve is a valve that allows fluid to flow in one direction only. Spring check valve also known as one way valve or non-return valve. The difference between a spring check valve and swing check valve is spring check valves can be used for vertical piping.

Spring check valves are two-port valves, one for fluid to enter (inlet port) and the other for fluid to leave (outlet port). When the fluid flow from inlet port, it will need at least 1 Bar working pressure to push the disc open for fluid to flow through. If there are any back flow from outlet port, it will push the disc back and block the fluid.

There are various types of check valves used in a wide variety of applications. The operation of spring check valve do not require any valve handle or stem as long as there are 1 Bar working pressure from the fluid flow. It is available in stainless steel SS316 material for better corrosion resistance.
