The DIG 3/4" DC Valve with Flow Control is a heavy-duty inline irrigation valve designed to operate reliably where traditional electrical power isn't available. Equipped with a DC latching solenoid, this valve is engineered to be paired seamlessly with battery-operated irrigation timers, making it the perfect solution for remote garden beds, highway medians, or properties without an outdoor AC outlet.
Don't let the battery operation fool you—this valve is built to handle professional demands. It features a rugged, glass-reinforced nylon body capable of withstanding pressures up to 150 PSI. The internal self-cleaning diaphragm ensures continuous operation even when pulling from slightly contaminated water sources. Combined with a smooth open/close mechanism that prevents destructive pressure surges, this valve offers superior hydraulic performance in a compact footprint.

Follow these steps to securely install your battery-operated valve.
Step 1: Install the Enclosure
As an inline valve without an atmospheric vacuum breaker, it must be installed underground inside a protective plastic valve box. Ensure the box is large enough to house both the valve and your battery-operated controller.
Step 2: Connect to Mainline
Wrap Teflon tape around your 3/4" male PVC threaded adapters and screw them into the valve's inlet and outlet ports. Verify the directional arrow on the valve body points downstream.
Step 3: Wire the DC Controller
Splice the two wires from the DC latching solenoid directly to your battery-operated controller. Use silicone-filled waterproof wire nuts to ensure the connection won't short out in the damp valve box.
Step 4: System Flush
Turn on the main water supply. Open the internal bleed to manually activate the valve, flushing out dirt or PVC glue residue. Close the bleed, test the timer activation, and adjust the top flow control handle as needed.
Can I wire this DC valve to my standard plug-in irrigation timer in the garage?
No, this valve features a DC (Direct Current) latching solenoid. It will only operate when wired to a battery-powered irrigation controller. Connecting it to a standard 24V AC plug-in timer will instantly destroy the solenoid.
How does a DC latching solenoid save battery life?
A DC latching solenoid only uses a tiny pulse of battery power to magnetically "latch" the valve open, and another tiny pulse to close it. It does not require continuous battery drain to stay open during the watering cycle.
Does this valve prevent backflow into my drinking water?
No, the DIG 3/4" DC valve is an inline globe valve. It does not contain an internal anti-siphon mechanism. Depending on local codes, you may need to install a separate backflow preventer upstream from this valve.
Why is mid-May the ideal time to install a battery-operated DC valve?
As mid-May warmth hits and new spring garden beds are established far from the house, installing a DC valve allows you to easily automate watering in those remote areas without the massive expense of trenching electrical wire across your yard.
