The Dome Valve is an extreme open-close valve for use in harsh abrasive environments. It provides open-close and pressurize capability time and time again, operating where other valves simply fail. We are the original patent holders of the Dome Valve. Our founders designed this valve in the 1970′s and have proved the design through extensive R&D and testing. Today the valve sees service in the harshest of environments all over the world.
