Type 84 innovative valve design provides leak-tight performance for H2 storage, transportation, refueling station and high-pressure gas applications.
Type 84 direct spring pressure relief valve delivers exceptional leaktight performance for high-pressure gas applications up to 21,756 psig (1500 barg).
Type 84 ensures safe and reliable operation of H2 storage and transportation, H2 refueling stations, and other high-pressure gas applications in Hydrogen, Air Separation and Oil and Gas industries.
Soft seat design provides repeatable bubble-tight performance before and after each relief cycle.
Leak-tight performance near set pressure allows higher operating pressure, resulting in increased process throughput and system optimization.
Leak-tight performance near set pressure allows higher operating pressure, resulting in increased process throughput and system optimization.
Easily replaceable soft seat and seals eliminate expensive, time-consuming lapping of metal components, resulting in lower long-term maintenance costs.
Externally adjustable blowdown on Types 81/83 allows precise adjustment of reseat pressure without affecting set pressure adjustment.
Types 81/83 provide full lift at set pressure with no overpressure required.
Minimizes possibility of freeze-up in applications involving a cryogenic or refrigerant and allows for D.O.T. applications to be set higher than Maximum Allowable Operating Pressure.
Type 81P spindle design balanced against the effects of back pressure without the use of a bellows, reducing both initial purchase and associated long-term maintenance costs.
Meet ASME Section VIII and Section XIII requirements, providing the user with third party verification of valve capacity and performance.
