The Sarasin-RSBD® 74 Series Pilot Operated Pressure Relief Valve provides the capability for the protection of storage vessels, tanks, and piping systems under low pressure and vacuum conditions.
The Sarasin-RSBD® 74VP, 74LP, & 78LP Series Pilot Operated Pressure Relief Valves are autonomous units and therefore they do not need an external source of power to operate. Pilot operated pressure relief valves are most effectively used within liquefied natural gas and floating liquefied natural gas industries. The valves are also effective in processes involving petrochemical refinement and the power industry. The Sarasin-RSBD® pressure relief valves are designed to provide excellent operational performance and repeatability by their use of precision machined internal components and high integrity soft goods.
