Cameron 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 contact; 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 B16.10.
