Parker - Refrigerating Specialties: 111636, SRV, CSRH1 250 PSIG 1/2X3/4

Parker's cartridge safety relief valves (CSRV) are designed to offer the highest level of protection while maintaining easy serviceability. The CSRV was designed from the existing Parker SR and SRH safety relief valve housing, which allows for a simple and easy upgrade path to the new cartridge based design. As local or state codes govern the frequency of valve replacement, the CSRV is a cost effective alternative to standard safety relief valve designs. Typical applications for the CSRV include compressor packages, accumulator vessels and anywhere else protection from overpressure is required.Product Features:Suitable for ammonia and halocarbon refrigerantsASME Boiler and Pressure Vessel Code, Section VIII, Division 1 compliantANSI/ASHRAE 15 safety standard for refrigeration systemsStainless steel cartridge and internal componentsSame lay in length as SR and SRH series safety relief valvesCartridge based design allows for replacement while housing remains in the systemNon-stick PTFE seatSet pressure tolerance of ±3%Unaffected by vibrationApplication:Compressor PackagesAccumulator VesselsAnywhere else protection from overpressure is required
