SEBIM® CSSV 3000 COMPACT SINGLE SAFETY [...]
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.
The Sarasin-RSBD 71 SERIES design has been developed for customer who want to protect piping or vessel against thermal expansion overpressure in gas service, keeping operating pressure close to the set pressure.The Sarasin-RSBD 71 SERIES design is based on thermal expansion spring-loaded body design (9 SERIES) The Sarasin-RSBD 71 SERIES are an engineered custom-made design that has been industrialized and offer FULL NOZZLE Pilot Operated Pressure Relief Valve in Industrial Gas Service:
- FULL NOZZLE version is better to insure body chemical protection
- In case of upgraded process (higher backpressure / higher operating pressure) customer can simply go from Spring Loaded to Pilot Operated version keeping the same center-to-face dimension.
- FULL NOZZLE version are integral wetted components which offer the advantage of removal for maintenance and replacement.
