WOMâ€™s Dual Seal Ball Valve is the only trunnion mounted ball valve with two independent seats on both sides of the ball. The Primary Seat take the normal wear and tear when the valve is cycled. If it ever gets damaged the Secondary Seat takes over. This redundant sealing technology can more than double the useful life of the valve.
Even after the Primary Seat gets damaged, it will continue to work as a wiper ring. Each time the valve is cycled the Primary Seat will clean trash and line debris off of the ball before it can damage the Secondary Seat.
Designed to replace thru-conduit gate valves in mainline service. Ideal for manifolds, tank farms, pig launchers, river crossings, hot-taps or any other application where a positive, bubble-tight seal is required. The Dual-Seal Ball Valve is capable of acting as an emergency shut-down valve when used with a fail-close actuator.
