City Gate / District Station Regulators

 

Type 99 Pressure Reducing Regulator

The Type 99 regulator typically provides fuel gas to boilers, furnaces, ovens, mixers, and large commercial or institutional installations.

The key to the operation of a Type 99 regulator is the yoked double-diaphragm pilot. Fast response and accuracy are made possible by the amplifying effect of the pressure-balanced pilot and by the two-path control system. The function of the pilot is to sense change in the controlled pressure and amplify it into a larger change in the loading pressure . Any changes in outlet pressure act quickly on both the actuator diaphragm and the loading pilot, thus providing the precise pressure control that is characteristic of a two-path system.

Type 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 Series pilot, 161AY Series pilot or a PRX Series pilot.  For applications that have high pressure drops, using a Type 161AYM, 161EBM, or 161EBHM monitor pilot will increase the accuracy of the regulator.

Type 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.
