FireSeal Ventilation Valve Closures

FireSeal Ventilation Valve Closures
Our FireSeal Ventilation Valve Closures are used in low pressure systems for containment of gasses and fluids where air or water-tight closure is essential.  They are entirely made in America and machined in our production facility in Kent, Wa.  They are built to NAVSEA standard drawings, are easy to install and will last the life of the ship.  These valves provide a fire-proof boundary with special seals that ensure compartment integrity.  The lug system allows for easy installation for the pipefitter and are beefy enough to not warp.
