Reliability

3

Reliability of valve operation affects service life and ease of inspection and maintenance. In order to predict reliability, a sound valve design must be backed up by a stress analysis and functional qualification testing under critical operating conditions.

A double spring-energized metallic O-ring seatprovides a static (1) and dynamic seal (2) aswell as the inherent fire safe function.Each O-ring has a double envelope, the innerone in stainless steel, the external one in copperor 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 tighteningscrews are secured by a jam nut and can't belost inside the piping.

This design allows easy and quick in-linemaintenance.Thanks to the window placed on the side ofthe valve, free access inside the valve is possible for inspection and maintenancewithout disaccoupling the actuator.No special tool is required.
