USUN Model : FRV Similar Butech High pressure safety relief valve for complete test equipment
USUN relief valves feature a repeatable pressure release design and set the standard for safety in high-pressure
applications, where maximum safety and reliability are critical. The cost saving design minimizes the need for
frequent recalibration, resulting in reduced maintenance and downtime. Set at the factory based on customer
requirements, precalibrated, tagged and locked in.
Valve product features
Lower whole-life cost • Repeatable release minimizes need for frequent re calibration •
Optimized outlet flow for faster relieving.
Proportionally actuated
• Constructed of 316 SS, Nitronic 60 and 17-7 spring as standard
• Alternative spring material: 316SS, Inconel 718
Capable of handling air, gases, steam, vapor and liquids, the valves are not fire rated and not suitable for steam boiler
applications, nor on pressure vessels CAT III, IV. Valves are not ASME code stamped safety devices. Standard model
not suitable for oxygen service. Consult factory for alternative material.
Product applications
Engineered to provide reliable, repeatable venting of gases or liquids in pressure gas systems,
cryogenic systems and petrochemical applications where flow is not important.
