APPLICATION: Regulation of inlet pressure to gas compressors. Control of supply or distribution system pressure
PRESSURE RANGE: Ductile Iron: Upstream: 10 psig to 125 psig Downstream: 5 psig to 125 psig Ductile Iron: Upstream: 10 psig to 300 psig Downstream: 10 psig to 300 psig Steel: Upstream: 10 psig to 300 psig Downstream: 10 psig to 300 psig CAPACITY: Refer to Table of Contents
OPERATION: The Pilot Assembly and Motor Valve Stem Assembly (Crosshatched) are the only moving units in the regulator. The PILOT PLUG consists of two stainless balls rigidly con-nected together. Upstream Pressure (Red) is the supply pres-sure to the pilot and is also in constant communication with the top side of the MOTOR VALVE DIAPHRAGM. The area of the MOTOR VALVE DIAPHRAGM is twice the area of the motor valve seat, assuring a positive shut-off. The lower seat for the PILOT PLUG is the Motor Valve Diaphragm Pressure inlet (Red to Yellow). The upper seat for the PILOT PLUG is the pressure vent (Yellow to Atmosphere). The PILOT SPRING loads the upper side of the Pilot Assembly and is opposed on the underneath side by the controlled Downstream Pressure (Blue). Assume the PILOT SPRING is compressed with the ADJUSTING SCREW for a desired Downstream Pressure set-ting. With Downstream Pressure (Blue) too low, the PILOT SPRING forces the Pilot Assembly downward to close the upper seat (Yellow to Atmosphere) and open the lower seat (Red to Yellow). This lets full Upstream Pressure (Red) load the under-neath side of the MOTOR VALVE DIAPHRAGM to balance the pressure on the top side. Upstream Pressure (Red) acting under the motor valve seat, opens the valve. As Downstream Pressure(Blue) increases to the set pressure Pilot Assembly assumes a position in which both seats of the PILOT PLUG are closed. Should Downstream Pressure (Blue) rise above the set pressure, the Pilot Assembly moves upward against the PILOT SPRING to open the pressure vent (Yellow to Atmosphere). Motor Valve Diaphragm Pressure (Yellow) decreases to reposi-tion the Motor Valve Stem Assembly. The intermittent bleed pilot, three-way valve action of the PILOT PLUG against its seat adjusts the Motor Valve Diaphragm Pressure (Yellow), repositioning the Motor Valve stem Assembly to accommodate any rate of flow. The rapid but stable reposition-ing produces a true throttling action.

Gas capacities are based on pressure taken immediately upstream and downstream from the regulator in a wide open position. Critical flow exists across a valve or orifice when the down-stream absolute pressure is approximately half of the upstream absolute pressure. Any decrease in downstream pressure will not increase the flow through the valve. Critical flow conditions on the charts are represented by the MAXIMUM CAPACITY LINE.
GAS CAPACITY CHARTS
200, 285, 300 & 500 psig Maximum W.P. Valves
HOW TO USE CHARTS: Locate UPSTREAM PRESSURE at left of chart. Follow horizontally across to PRESSURE DROP (upstream minus downstream pressure). Read VOLUME directly below. If the horizontal projection of the upstream pres-sure does not intersect the given pressure drop, flow is critical. In this case project UPSTREAM PRESSURE horizontally to the MAXIMUM CAPACITY LINE and read VOLUME directly below.
*For gravity correction multiply above capacities bywhere G equals specific gravity of gas.
