Our pressure-seal NEWCO 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.
In contrast with bolted-bonnet valves, internal pressure applied to a pressure seal valve forces the sealing elements into tighter contactâ€”the higher the internal pressure, the tighter the seal.
Pressure-seal NEWCO valves comply with the design and test requirements of ANSI Spec B16.34 and the installation dimensions of ANSI Spec B16.10.
