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.




Exceptional Leak Tightness and Safety

With a PTFE/cryogenic compatible soft seat and bubble-tight sealing, the REGO 9400 Series ensures maximum leak tightness at designated relief pressure. This reliability is vital for cryogenic storage systems, where safety and containment of gases like LNG, nitrogen, and oxygen are critical.


Optimal Performance and Durability

Machined from high-quality brass and featuring stainless steel internal components, these relief valves resist corrosion and support reliable, long-term cryogenic service. The spring-loaded, vertically-mounted design enhances performance by minimizing back pressure and ensuring precise regulation.

FAQ's of REGO Cryogenic Gas Relief Valves, Non-ASME 9400 Series:


Q: How should the REGO 9400 Series Cryogenic Gas Relief Valve be installed for best results?

A: For optimal safety and performance, the valve should be mounted in a vertical position with upward discharge. This orientation helps maintain bubble-tight sealing and reduces the risk of backflow, as recommended by the manufacturer.

Q: What cryogenic gases are compatible with the REGO 9400 Series relief valve?

A: These valves are suitable for use with multiple cryogenic gases, including oxygen, nitrogen, argon, carbon dioxide (CO2), and LNG. Their PTFE/cryogenic compatible soft seat ensures effective sealing and longevity in these applications.

Q: When is it necessary to adjust the set pressure on the relief valve?

A: Adjustment of the set pressure may be required when changing system operating parameters or replacing the valve in a different application. The REGO 9400 Series allows for easy external adjustment, but should always be set within the factory-recommended range of 50 psig to 550 psig.

Q: Where are REGO 9400 Series relief valves typically used?

A: They are frequently installed in cryogenic storage tanks, piping networks, and transport trailers across various industrial sectors in India and worldwide. Their reliable performance and corrosion resistance make them ideal for demanding cryogenic services.

Q: What maintenance process is recommended for these relief valves?

A: Regular inspection for corrosion, seal integrity, and pressure settings is advised. Replacement seat kits are available to refurbish worn sealing surfaces, prolonging service life and maintaining bubble-tight performance.

Q: What is the primary benefit of using a spring-loaded design in these valves?

A: The spring-loaded design effectively controls relief pressure and minimizes backflow, ensuring safe discharge and reliable operation under fluctuating pressure conditions common in cryogenic environments.
