Military Grade VentChek Valve

The VentChek Valve is an anti-siphon valve for internal venting of ship plumbing systems. In use on new U.S. Navy ships, VentChek eliminates thousands of feet of vent piping and numerous deck penetrations. It features a high-performance elastomeric seal that opens momentarily to break the siphon caused when a plumbing fixture is drained. 

VentChek has been tested to military-grade shock, vibration, and acoustic standards. The valve body is cast from naval bronze and is designed to provide years of maintenance-free service in marine applications.
