Alloy Steel Double Flapper Check Valve For Coiled Tubing 10000psi Working Pressure

Introudction of CT Check Valve

The double flapper check valve is applied the coiled tubing operation in oilfield, the check valves are the standard part of the coiled tubing string, when the coiled tubing string or surface equipment is failed to work or damaged, the double flapper check valve will prevent the down-hole liquid refluxing into the tubing string.

The double flapper check valve featured with dual seal deisgn to improve the reliable of the sealing, the elastomeric seal is mainly for the low pressure sealing and the metal sealing is for the high pressure sealing during the coiled tubing operation.This sort of flapper check valve can be utilized on low or high-pressure applications.

Features of the Double Flapper Check Valve
