10FCO/10FCOS/10FCON, 10K Cast Iron Swing Check Valve

The check valve is a valve that constantly maintains fluid flow in a constant direction and prevents reverse flow.The disc is pushed open by the fluid pressure, but when it flows backward, the disc is brought into close contact with the seat of the body by the back pressure to prevent backflow.There are three typical types of check valves (swing check valve, lift check valve, and wafer check valve).
