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.
