API 6A Flapper Type Check Valve For High Pressure Pipe Line Flow Control
Check Valves are important part of wellhead equipment and widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety.
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.
