The Rain Bird DVF 25mm solenoid valve controls water flow to irrigation zones using a compatible 24V AC controller. Its flow-control handle adjusts water flow at the valve.
The double-filtered pilot circuit helps keep debris out of the valve’s control passages. A captured solenoid plunger and captive diaphragm spring help prevent lost parts during servicing.
To open the valve manually, turn the solenoid handle anticlockwise 1/4 to 1/2 turn. Turn the handle clockwise to close the manual control and restore controller operation.
Internal manual bleed releases pressure above the diaphragm into the outlet pipe, allowing the valve to open without an electrical signal. Water stays within the pipework. Close the manual control after testing to return the valve to controller operation. The external bleed screw releases water outside the valve for flushing during installation and start-up. Keep it closed during normal controller operation.
For drip irrigation or flows below 12.5 L/min, install the upstream filter specified in the linked instructions.
