WC6 WC9 C5 API598 Cast Steel Threaded Check Valve API 6D ANSI B16.34 BS 1868

Descrition:

Check Valve, also known as a one-way valve or Check Valves. Pipeline used to prevent reflux of a fluid valve. So pipeline fluid can only make one-way flow of fluid when the clock back, the flap valve can be shut down automatically to prevent backflow.
