The Type EZR pilot-operated, pressure reducing regulator is designed for natural gas transmission/ distribution
systems and industrial/ commercial applications. 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 regulators, and the specially engineered flow path deflects debris, protecting the seat from damage
and erosion. The Type EZR is used in conjunction with a 161EB or 161AY Series pilot and Type 112 restrictor or
with a Series PRX pilot ( with integral restrictor) . The Type EZR pressure reducing regulator can be converted to a
high pressure relief valve or backpressure regulator by simply changing to a relief piloting system ( refer to Bulletin
71.4: EZR) . An optional inlet strainer prevents large particles from entering the main valve limiting damage to
internal parts. A Type 252 pilot supply filter ( optional) can be added to keep pipeline debris from entering the pilot.
For underpressure and/ or overpressure protection, the Type EZR is available with an integral slam-shut device.
