Redundant valve manifolds serve Safety Instrumented Systems

摘要

Critical process control is delivered to Safety Instrumented Systems by new RVM redundant valve manifolds where unscheduled shutdowns are unacceptable. RVM is announced as one of the first to offer a two out of three (2oo3) configuration: If one of the three pneumatic logic circuits should malfunction, there are two logic circuits still operational, so critical redundancy is maintained.
