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. The valve can be ordered with set pressures ranging from 10 to 750 Psig (0.7 to 51.7 Bar) and come factory preset and permanently locked. 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. 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)

Parker Bestobell’s cryogenic safety relief valves are designed to protect cryogenic static and road-going storage tanks or capital equipment from damage caused by over-pressure.

These cryogenic safety relief valves feature an innovative proportional lift action which ensures that when the pressure in a tank rises, the safety relief valve activates and releases pressure gently to enable it to drop back to a safe pressure.

They are available in three basic sizes defined by the throat diameter and are available with a variety of inlet and outlet connections. The valves are designed and factory set to lift repeatedly within +/- 2% of the set pressure and to re-seat above 92% of set pressure. Spring pre-compression and blow-down ring settings are securely sealed and factory set after testing to inhibit unauthorised tampering, as these are Category Four safety products. Flow rates at 10% above set pressure are measured to ensure compliance with stated flow capacities as an additional safety precaution.

• Designed to comply with ISO 4126 (Safety Valves General Requirement), Ad-Merkblatt A2 (Safety Devices against Excess Pressure) and TUV requirements.

WARNING:Inspection and maintenance of pressure relief valves is very important. Failure to properly inspect and maintain pressure relief valves could result in personal injuries or property damage. The useful safe service life of a pressure relief valve may be significantly affected by the service environment.

Pressure relief valves (PRVs) are a necessary requirement for overpressure protection within the LNG industry. However, not all PRVs are created equally when it comes to performance within cryogenic applications, and design temperatures as low as -320˚F (-196˚C). These applications require PRVs with enhanced sealing features to address the cryogenic conditions and perform their safety function.

In this article published in the August 2020 edition of LNG Magazine, Author Matt Byers, Senior Product Manager, Baker Hughes, USA, outlines the engineering best practices used today to optimize the design of pressure relief valves operating under cryogenic conditions.

Pressure relief valves have high flow capacity in order to be capable of efficiently directing flow to tanks. They"re used in hydraulic systems, and limit system pressures at specific levels. When a prescribed set pressure limit is reached, a pressure relief valve will immediately respond by sending excess flow from the system back into the tank.
