Sarasin-RSBD 86 Series Pilot Operated Pressure Relief Valve
The Sarasin-RSBD 86 SERIES FULL NOZZLE design is based on our experience in NUCLEAR applications. It has been developed to protect drum, superheater and to comply with local regulation where isolated steam from atmosphere and remote sensing line are mandatory statement.
The Sarasin-RSBD 86 SERIES Pilot Operated Pressure Relief Valve has been developed to high temperature steam requirements.
This new design and material is based on our extensive experience in nuclear applications. The DMS technology is the same as than currently used by SEBIM in NUCLEAR power plant.
The design of the valve seal is performed without any elastomer. The main valve dome and DMS pilot sealing is insured by metallic bellows. This feature allows the Pilot Operated Pressure Relief Valve to keep a constant steam flow through the DMS pilot and the main valve without any impact on valve performance.
“Hang-up” of guiding surfaces associated with comparable valves is eliminated with a unique anti-sizing feature. the first Pilot Operated Pressure Relief Valve in the world to offer this technology to prevent such kind of failure.
