Sarasin-RSBD®
Starflow (P Series) Pressure Relief Valve
The Sarasin-RSBD® Starflow Spring Loaded Pressure Relief Valve is designed using the concepts of safety, high performance, interchangeability, and simplicity for oil and gas applications.
The Starflow range of Spring Loaded Pressure Relief Valves are available in both conventional and balanced bellows designs.
These Sarasin-RSBD® safety relief valves feature a wide range of material options and trim designs to meet the demands of many processes and applications.
Starflow spring loaded pressure safety valves can be used in vapor, gas, liquid, or steam applications in the oil and gas industry as well as cryogenics. The valves are designed to provide high integrity performance and repeatability by their use of an integral full, one-piece nozzle, a self-aligning top-guided disc & disc-holder, and a single adjusting ring for blowdown setting.
