LOW PRESSURE MOTOR VALVES
DOUBLE ACTING
APPLICATIONS: Liquid metering vessels. Any system which requires a valve to receive a pilot signal on either or both sides of the main diaphragm.
FEATURES: Tight shut-off Single soft seat Full line size opening Removable valve seat Ratio of diaphragm to seat area is 2:1 Spring loaded to hold 5 to 6 p.s.i. back pressure Minimum Maintenance All internal parts can be removed with valve in line
CAPACITY: For liquid capacity charts refer to table of contents. For gas capacity charts refer to catalog section “A”.
CONSTRUCTION: Materials in body and housings are made of cast iron, duc-tile iron or steel. Valve stem is 303 stainless steel. Spring is stainless steel. Diaphragm and seating materials are oil resistant synthetic rubber. After assembly each valve is given a complete operational test.
OPERATION: The Stem Assembly is the only moving unit in the double acting motor valve. The PRELOAD SPRING loads the Stem Assembly closing the valve if there is no Diaphragm Pressure (Yellow) and if Upstream Pressure (Green) minus Downstream Pressure (Blue) is 5 to 6 psig or less. An increase in the Diaphragm Pressure (Yellow) and / or and increase in the differential pressure across the INNER VALVE SEAT overcomes the PRELOAD SPRING force, moves the Stem Assembly upward, opening the valve. A decrease in the Diaphragm Pressure (Yellow) allows the PRELOAD SPRING to move the Stem Assembly downward and close the valve when Upstream Pressure (Green) minus Downstream Pressure (Blue) is 5 to 6 psig or less. With an effective DIAPHRAGM area two times the INNER VALVE SEAT area, and the PRELOAD SPRING, a differen-tial pressure greater than 5 to 6 psig and/or 3 psig or more Diaphragm Pressure (Yellow) will open the motor valve.
