EZR Relief Valve or Backpressure Regulator Gas Modular Skid Fish-.er LNG Skid Mounted Gas Device Solution Power Tool Sets

An introduction to some of the options of pressure reduction and safety protection equipment in the control of gas supply.There are many combinations of regulators and associated safety protection
equipment used throughout the world - and no one type suits all applications.

The correct sizing of the relief valve is vital and is to cover the total capacity of
the installation- and to be based upon the following -
V Maximum inlet pressure
r Minimum setting of the relief pressure
r Maximum capacity of the regulator (with correct size valves or orifice if
fitted). This is not the capacity in the standard manufacturers performance
data tables - as these show in the in-control flow / with accuracies of say
5%, 10% or 20%. But the fully wide open regulator capacity (with correct
orifice or valve size) to calculate the size relief valve at the worst possible

A relief valve has a set point at which it begins to open.
For the valve to fully open and pass the maximum flow, pressure must build
up to some level above this set point of the relief valve to pass a capacity.
Some manufacturers give the capacity at 10% or 20% or 50% above the
setting point of the relief valve. 


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.



•Quiet Operation—The standard cage provides best-in-class noise reduction, making the EZR Series 6-8 dBa quieter than comparable flexible element regulators.
•High Capacity—The flow path of the EZR Series produces best-in-class capacity combined with the quietest operation. Fisher™ products are laboratory tested so 100% of the published flow capacity can be used with confidence.
•Long Life—The field proven dipahragm design incorporates layered fabric, a raised bead edge and molded shape to increase strength, durability, and service life
•Debris Protection—The revolutionary flow path of the EZR Series cage minimizes the damage from debris while the stainless steel inlet strainer prevents large particles from damaging the diaphragm.
•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.
•Travel Indicator—Simplifies in-service inspection and system troubleshooting
•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.

•Pilot-operated, flexible element regulator

• Top-entry design allows easy in-line maintenance

• Protected flexible element

• Top entry, easy in-line maintenance
