Fisher Type EZR 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. It provides smooth, quiet operation, tight shutoff, and long life, even in dirty service.

Features

1.Quiet Operation—The standard cage provides best-in-class noise reduction, making the EZR Series 6-8 dBa quieter than comparable flexible element regulators.

2.High Capacity—The flow path of the EZR Series produces excellent capacity combined with the quietest operation. Fisher™ products are laboratory tested so 100% of the published flow capacity can be used with confidence.

3.Long Life—The field proven dipahragm design incorporates layered fabric, a raised bead edge and molded shape to increase strength, durability, and service life

4.Debris Protection—The revolutionary flow path of the EZR Series cage reduces the damage from debris while the stainless steel inlet strainer prevents large particles from damaging the diaphragm.

5.Tight Shutoff—The metal plug is designed to deflect particles and debris away from the diaphragm, providing superior shutoff and increasing the time between maintenance intervals.

6.Travel Indicator—Simplifies in-service inspection and system troubleshooting

7.Versatility—By changing from a relief piloting system to a pressure reducing piloting system, a Type EZR relief valve or backpressure regulator easily becomes a pressure reducing regulator.
