A double spring-energized metallic O-ring seatprovides a static (1) and dynamic seal (2) as well as the inherent fire safe function. Each O-ring has a double envelope, the inner one in stainless steel, the external one in copper or nickel alloy. The spring is made of Inconel. The flexible retaining ring (3) ensures a comple- mentary contact pressure onto the disc. Thanks to a special arrangement, the tightening screws are secured by a jam nut and can't be lost inside the piping. This design allows easy and quick in-linemaintenance. Thanks to the window placed on the side of the valve, free...
