Conval Clampseal Globe Valve


The Conval Clampseal® product line includes Angle, Y, and T pattern globe and check valves, modularly designed to allow for in-line repairability in high-pressure and high-temperature applications.

A pressure-actuated backseat provides valve integrity by ensuring a positive internal stop and extends packing life by isolating the packing from the pressure when the valve is fully open. The pressure seal bonnet provides easy access for servicing with no welds to cut or seal rings or gaskets to replace. Replacement parts are low in number, common across valves sizes, and readily available. Available in fire-safe design.
