Recommended Wire Run Distances

The tables below are designed for quick reference and are set up to provide maximum wire runs, given the wire size for both the power and common wires. Maximum one-way distance in feet between controller and valve heavy-duty solenoid: 24 VAC, 360 mA inrush current, 230 mA holding current, 60 Hz.

NOTE: The tables represent a single active solenoid. The wire distances should be halved with two solenoids operating simultaneously on the same wires.

You may be able to activate a valve beyond the range listed, however doing so may damage the solenoid or cause other issues.
