Unique design of Pressure Seal Check Valve

Pressure Seal check valves are designed for reliability in high velocity service applications to prevent backflow. Pressure seal check valves rely on the flow of the medium itself automatically open and close the valve,Then in order to prevent the media back.

Sedelon?cast steel, Stainless steel and alloy steel ,pressure seal check valves are ideal for standard and critical power industry applications. The pressure seal bonnet joint eliminates the body/bonnet flanges, reducing weight and simplifying the application of exterior insulation. Contrary to bolted bonnet valves, internal pressure applied to a pressure seal valve forces the sealing elements into tighter contact – the higher the internal pressure, the tighter the seal.

Self sealing pressure range:Cast Carbon , Stainless steel or alloy steel ASME class 600 to 2500
