  • Irrigation valve with three-way solenoid actuation train
    Patent number: 10571040
    Abstract: An irrigation valve incorporates a valve body with an inlet, an outlet, a pressure chamber and a standpipe in fluid communication with the inlet. A solenoid operated valve train has a flow control inlet fitting, a solenoid actuating element movable between in inactivated position and an activated position responsive to a solenoid coil, and a threaded manual actuator rotatably movable between a first sealing position and a second open position. The valve train is operable in a first position with the solenoid actuating element in the inactivated position to produce hydraulic interconnection between the standpipe and the pressure chamber, a second position with the solenoid actuating element in the activated position producing hydraulic interconnection between the pressure chamber and an outlet port, and a third position with the threaded manual actuator in the second open position producing hydraulic interconnection between the pressure camber and the outlet port.
