Product Description

Premium performance direct spring operated pressure relief valves that use special internals and soft seats to provide optimum, accurate performance

Features

  • 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.
  • 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.
  • Comply with the EC Pressure Equipment Directive 2014/68/EU.
