Flapper Check Valves – Clapper check valves are designed for well service applications such as fracturing, cementing and acidizing. The flapper check valve is placed in the treating line to allow flow to the well but isolates and back flow to go upstream in the valve. This provides a safety device at various locations in the flow line and assure that pressure and fluid can not backup into the manifold or into pumps.

                                           

The check valves provided by CCSC are available in size ranges in 2", 3" and 4", in pressure ranges from 6,000psi to 20,000psi with hammer union end connections.
