Webb23 apr. 2024 · A HIPPS includes sensors, a logic solver and final elements — solenoid, actuator and process control valve — to shut off the source of over-pressure. A HIPPS is designed to act as quickly and reliably as a relief valve without the environmental and safety issues. Safety Integrity Levels Webb3.5 2oo2 Architecture – Diagnostic Coverage = 90% The 2oo2 architecture consists of two valves piped in parallel. This arrangement is counter-intuitive for safety because both valves must close to provide the safety function. This arrangement provides maximum protection against a false trip caused by a safe valve failure.
