HQV1 G1/4 Normally Closed 12 V DC Water Valve

Add an electrically controlled switching point to a small water line with the HQV1 valve. Its normally closed design keeps the flow path closed while the valve is not energised.

Switch a Compatible Water Line Electrically

• ✅ Control flow from a suitable circuit - The 12 V DC coil lets a matching controller operate the water valve.
• ✅ Close the flow path when unpowered - The normally closed configuration returns the valve to its closed state without energising the coil.
• ✅ Plan a compact connection - G1/4 ports and an approximately 40 × 30 × 60 mm body help you check the space and fittings needed.

Match the valve's 12 V DC supply, threaded ports and pressure range to the installation before fitting. Its exposed lead ends require a suitable electrical connection and protection appropriate to the location.

The package contains one two-way water valve with the pictured small silicone pads. This is a valve component; a power supply, controller and water tubing are separate.

One HQV1 water valve with the pictured small pads; power supply, controller, fittings and tubing are not included.
