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 PRX Series 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.
