Fisher EZR Relief

The 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. 

The 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 valve and backpressure regulators. The specifically engineered flow path deflects debris, protecting the seat from damage and erosion.
