Product Description

Check Valves are installed in high pressure lines to stop reverse flow by the automatic close of flapper or dart.
Flapper check valves include top-entry check valves and in-line flapper check valves, which allow fluids to flow towards the wellbore and prevent flowing backwards. 
We provides both standard and reverse-flow check valves. And we have also developed check valves for sour service in accordance with NACE MR0175.
