    詳細介紹

    APPLICATION:
    Vent lines or pressure regulation on separators, heater
    treaters, compressor stations, gas gathering and distribution systems
    where it is desired that no gas be vented.
    ? Inside Buildings
    ? In populated areas
    ? Emissions regulated areas
    ? Sour or poisonous gas systems
    PRESSURE RANGE:
    3 psig to 300psig
    OPERATION:
    Assume the PILOT SPRING is compressed with the ADJUSTING SCREW for a set pressure greater than theUpstream Pressure (Red). The Pilot Assembly is forced downward by the PILOT SPRING. The lower seat for the PILOT PLUG (Yellow to Blue) is closed and the upper seat for the PILOT PLUG (Red to Yellow) is open. This lets full Upstream Pressure (Red) load the MOTOR VALVE DIAPHRAGM to close the valve.
    As the Upstream Pressure (Red) increases to the set pressure, the Pilot Assembly moves upward against the PILOT SPRING to first close the upper seat (Red to Yellow) and open the lower seat (Yellow to Blue). Motor Valve Diaphragm Pressure (Yellow) is vented to the Downstream (Blue).
    As the Motor Valve Diaphragm Pressure (Yellow) is decreased, the Upstream Pressure (Red) acting under the motor valve seat, opens the valve. With relief of the Upstream Pressure (Red) through the valve, the Pilot Assembly assumes a position in which both seats of the PILOT PLUG are closed.
    Motor Valve Diaphragm Pressure (Yellow) is regulated by the intermittent bleed pilot three-way valve action of the PILOT PLUG to reposition the Motor Valve Stem Assembly for changes in flow rate. The rapid but stable repositioning produces a true throttling action.
