1 OUNCES PRESSURE REGULATOR VACUUM BACK PRESSURE TO VACUUM APPLICATIONS: Vacuum distribution systems, compressor suction regulation to prevent excessive vacuum on wells. A minimum of 10 psi instrument gas is required. FEATURES: Intermittent vent pilot Soft seat for bubble tight shut-off High capacity (full opening seat) Uses external supply to isolate process stream from control pressure PRESSURE RANGE: Upstream: 0.1" to 5" Hg.Vacuum (additional spring ranges available to 30 Hg.) Downstream: Vacuum must be greater than upstream vacuum OPERATION: This valve maintains an upstream vacuum level at a set point (prevents excessive vacuum) by modulating to a greater vacuum downstream. The only moving parts are the Pilot Assembly and the Motor Valve Stem Assembly (Crosshatched). The three-way pilot action is due to the operation of the PILOT PLUG. The PILOT PLUG consists of two stainless balls rigidly connected. The upper PILOT PLUG seat is the Motor Valve Diaphragm Pressure vent (Yellow to Atmosphere). The lower PILOT PLUG seat is the Supply Pressure inlet (Violet). The Pilot Assembly actuates the PILOT PLUG. The combined forces of the PILOT SPRING and the Upstream Vacuum (Red) above the PILOT DIAPHRAGM working against atmosphere below the PILOT DIAPHRAGM determine the motion of the Pilot Assembly. Assume a desired Upstream Vacuum (Red) greater than the current vacuum. The ADJUSTING SCREW compresses the PILOT SPRING. The PILOT SPRING forces the Pilot Assembly downward. First, the upper PILOT PLUG seat (Yellow to Atmosphere) closes, then the lower PILOT PLUG seat (Violet to Yellow) opens. Increased Motor Valve Diaphragm Pressure (Yellow) below the MOTOR VALVE DIAPHRAGM Equalizes Supply Pressure (Violet) above the MOTOR VALVE DIAPHRAGM, allowing Upstream (Red) to move the Motor Valve stem Assembly upward. The motor valve opens. Assume Upstream Vacuum (Red) increases. The increased Vacuum pulls the Pilot Assembly upward against the PILOT SPRING. This first, closes the lower PILOT PLUG seat (Violet to Yellow), then opens the upper PILOT PLUG seat (Yellow to Atmosphere). Motor Valve Diaphragm Pressure (Yellow) decreases, Supply Pressure (Violet), action above the MOTOR VALVE DIAPHRAGM, pushes the Motor Valve Stem Assembly downward. The motor valve closes. This rapid but stable interaction of the Pilot Assembly and Motor Valve Stem Assembly produce a true throttling action accommodating any rate of flow.
