pilot operated safety valve

Safety relief valve: Safety valve that opens quickly after use (pop action), or according to increase in pressure. In other words, a common term. Pilot operated 

The replacement of direct spring-operated pressure relief valves (PRVs) with pilot-operated safety relief valves (POSRVs) can help plant operators streamline maintenance processes, reduce maintenance costs, address common valve performance issues, maintain safety and potentially increase output.

Mt.H has abundant experience and various achievements of Pilot Operated Safety Relief Valve in industrial plant projects and marine services.

The pilot operated safety valve offers a definitely superior performance, which – coupled with its perfect tightness – grants considerable savings 1) in the design and 2) in the operation of the plant itself. Suitable arrangement or adjustment allows the pilot operated safety valve to function properly even it the inlet pressure drop is very great.

Jean-Paul Boyer shares how pilot-operated safety valves (POSVs) used in LNG applications help to avoid leakage & enable safe operations.

The Consolidated Type 2900 pilot-operated safety relief valve combines the advantages of two products into one— the 1900 safety relief valve and the 3900 POSRV.

The main features of the pilot operated safety valves can be summarized as follows: Valves of a much larger size and higher set pressure than foreseen for spring loaded valves are available. The actual flow rate can be tailored to the requested capacity, by restricting the flow area and/or by using valves with modulating action.

The pilot valve, also called the “pilot”, is the control unit of the pilot-operated safety valve. It controls the function and behavior of the main valve.

Pilot operated safety valve This type of safety valve uses the flowing medium itself, through a pilot valve, to apply the closing force on the safety valve
