Type EZR Relief Valve or Backpressure Regulator
Fisher Type EZR pilot-operated, pressure relief valve or backpressure regulator


Fisher Type EZR pilot-operated, pressure relief valve or backpressure regulator is typically used in city gate and district stations as a relief valve for overpressure protection, or in commercial and industrial applications as a backpressure regulator. Type EZR provides smooth, quiet operation, tight shutoff, and long life, even in dirty service. Its internally actuated metal plug eliminates disadvantages associated with boot-style relief valves and backpressure regulators. The specially engineered flow path deflects debris, protecting the seat from damage and erosion. Type EZR relief valve or backpressure regulator can be converted to a pressure reducing regulator simply by changing to a pressure reducing piloting system (see Bulletin 71.2:EZR).
