[250 PSI]

The Generant Series Brass CRV, Cryogenic Relief Valve is a spring reference over pressure protection device. The CRV incorporates Generant’s exclusive “Dirt Guard” feature which increases the valves ability to tolerate particulate contamination. This device is ideally suited for use as a “Blocked Line Safety” in cryogenic systems. The CRV is supplied cleaned and packaged for oxygen service. Relief pressure can not be altered or adjusted in the field. Seat and poppet geometry combined with optimized spring ranges provide high flow rates with minimum pressure accumulation. The Generant Cryogenic Relief Valve has a compact design and availability of a variety of inlet and outlet configurations reduces size and piping requirements. Relief pressure can be discharged to atmosphere or to a downstream connection. The CRV is supplied with Flourosilicone seals for set pressures from 10 ? 49 Psig (0.7 ? 3.4 Bar) and PCTFE seals for set pressures greater then 50 ? 750 Psig (3.5 ? 51.7 Bar) FEATURES - Available CE marked in accordance to the requirements of the PED - Exclusive “Dirt Guard” poppet incorporates screen to extend valve and reliability - High Flow Capacity and Excellent Reseat Performance - Supplied Factory Preset Set and Permanently Locked for Tamper Proof Service - Discharge to Atmosphere or a Wide Varity of Inline Piping Configurations - Optional Deflector Cap available for diverting exhausted gas - 100% Factory Tested for Leakage, Crack and Reseal - Cleaned and Packaged for Oxygen Service Cryogenic Relief Valve (CRV) Technical Data Nominal Set Pressure Range 10 ? 750 Psig (0.7 to 51.7 Bar) Factory Set Tolerance**tolerance specifications per EN ISO 4126-1 Set Pressure ≤ 28.90 Psig, ± 5% Set Pressure 29.00 ? 48.30 PSI, ± 1.45 Psig Set Pressure ≥ 48.40 Psig, ± 3% Zero Leakage to 95% of Set Pressure Full Rated Flow @ 110% of Set Pressure Unaffected by up to 10% Back Pressure Materials of Construction Brass Body
