EZR Pressure Reducing Regulator



The Type EZR pilot-operated, pressure-reducing regulators are used for natural gas, air, or other non-corrosive gas applications and include a Type 112 restrictor and a 161EB, 161AY or PRX Series pilot. For applications that have high pressure drops, using a Type 161AYM or 161EB monitor pilot will increase the accuracy of the regulator.

EZROSX with Slam-Shut Device
The optional slam-shut device can provide either overpressure or overpressure and underpressure protection by completely shutting off the flow of gas to the downstream system. The slam-shut has a mechanism box and a manometric device. The manometric device is a spring and diaphragm actuator. Its movement activates the detection stage of the mechanism box. The shutoff is a two stage process, the detection stage and the power stage. This separation between detection stage and power stage provides maximum precision, alleviating many false trips caused by environmental vibrations.
