Hunter 44007890 Dc-latching Solenoid Irrigation Valves

Product Description

The HUNTER 44007890 is a DC-latching solenoid designed as a replacement actuator for Hunter irrigation valves. DC-latching solenoids operate differently from standard AC solenoids: they use a brief voltage pulse to open or close the valve, then hold that position without continuous power draw. This makes them well suited for battery-operated controllers and decoder-based irrigation systems where power conservation matters. The solenoid operates at a minimum opening voltage of 6 volts DC and a maximum recommended voltage of 9 volts DC, with a coil resistance of 4.8 ohms nominal and a pulse width of 250 milliseconds. Installation is handled by licensed irrigators or qualified irrigation technicians.

This solenoid is intended for use with Hunter irrigation valves in residential and commercial landscape irrigation systems. It is commonly installed as a field replacement when a valve fails to open or close properly due to a failed solenoid, without requiring replacement of the entire valve body. The 22-inch wire leads of 18 AWG black and red UL-approved wire provide adequate length for most valve box installations, simplifying connection to decoder or controller wiring.

Key Features

• DC-latching design holds valve position without continuous power, reducing battery drain in wireless and decoder systems
• Operating voltage range: 6 volts DC minimum to 9 volts DC maximum recommended
• Coil resistance: 4.8 ohms nominal for predictable current draw
• 250-millisecond pulse width for reliable open and close actuation
• 22 inches of 18 AWG black and red UL-approved wire leads included

Compatibility

Designed for use with all Hunter irrigation valves that accept a DC-latching solenoid. Verify solenoid type before ordering, as Hunter valves may use either AC or DC-latching solenoids depending on the controller and system configuration.

Installation Notes

Installation is typically performed by a licensed irrigator or irrigation technician. Before servicing, shut off the water supply to the valve and confirm the controller is powered down or that the zone is disabled. DC-latching solenoids are not interchangeable with standard 24-volt AC solenoids; confirm system compatibility before replacement. Follow local codes and manufacturer wiring guidelines when connecting to decoder or two-wire control systems.
