2000/03/31 · The rehabilitation of a leaking subsea check valve on an operating gas line operating at 1,160 psi was completed by Mexsub using a sleeve system to encase the valve. The repair, which was conducted in th of Campeche offshore Mexico, did not require shutting down the pipeline or reducing flow, or welding on the valve body.

WITT non-return valves conform to EN 746-2 and are particularly suitable for use in thermal processing plants. The low opening pressure of only 3 mbar and the 

High-quality gas non-return valves protect against dangerous gas backflow. Low opening pressure - leak-tight elastomere sealing system - long service life.
