Product Description

Product Description

Flow Line Check Valve

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. For dart check valves, the flow will open the dart by overcoming the small spring force.
When the flow runs in opposite direction, the spring will push the dart against the seat retainer to prevent reverse flow.
We provides both standard and reverse-flow check valves. And we have also developed check valves for sour service in accordance with NACE MR0175.

Features:

1. Check valves are suitable for isolating completion fluid, high pressure processing and rig equipment repairing.
2. The surface of valve internal baffle is covered with nitrile-butadiene rubber to extend life.
3. The thread and the joint of ball face adopts America standard.
4. The valve is casted by hard alloy steel and adopts union connection.
