Sarasin-RSBD® 76 Series Full Nozzle Pilot Operated Pressure Relief Valve (PRV)
The Sarasin-RSBD® 76 Series Full Nozzle Pressure Relief Valve (PRV) design has been developed for customers who want to protect the vessel against overpressure in cryogenic condition or insure body chemical protection.
Sarasin-RSBD’s® 76 Series design is based on API Standard 526 spring-loaded body design (P Series) including limited acceptable back pressure value. Therefore, the center-to-face dimensions and inlet & outlet rating meet API Standard 526 for spring-loaded valves.
In the API Standard 520 Part I, the selection of the nozzle type is only available for spring loaded pressure relief valves, not pilot operated pressure relief valves, which are designed with a semi-nozzle as a standard design.
