Abstract
A valve assembly comprising a pilot valve; a solenoid; and a main valve, the main valve having an actuator in communication with a pressure control; the pilot valve may facilitate opening the main valve in proportion to an energized level of the solenoid. The solenoid may move the first disc to isolate the inlet port from the pressure control and/or move the second disc to communicate the outlet port with the pressure control. The actuator may move the second disc to isolate the outlet port from the pressure control and/or move the first disc to communicate the inlet port with the pressure control. The pilot valve may isolate both the inlet port and the outlet port from the pressure control when the pilot valve experiences forces in equilibrium from the solenoid and the actuator.
