Flapper Check Valve / In-line flapper check valve
Check valves are used as isolation valves that permit
flow in one direction but stop flow in the opposite direction, to isolate well-servicing equipment from high-pressure treating fluids during fracturing applications. The flapper check valve provides a safety device in the flow line to assure that pressure and fluid cannot backup into the manifold area or into the pumps.
Flapper check valves are manufactured in 2" & 3" sizes for standard and sour gas environments. Each size is offered with hammer union end connections, and available in pressure ranges from 10, 000 psi to 15, 000 psi for well service applications such as acidizing, cementing and fracturing. Each check valve has a nameplate marked with size and pressure, and this working pressure corresponds to the maximum pressure acceptable for either end connection.
Seat and body of the valve are separate to assure the seat can be replaced fast and easily as needed. And carboxylated nitrile flapper face is abrasion resistant against a complete range of well fluids.
