Wireless Remote Flow Control Valves for Irrigation: Options and Limitations

Finding a wireless, remotely adjustable flow control valve for a ½" irrigation line with 100-foot range is challenging. As of now, no major manufacturer produces a standalone wireless proportional valve for residential/commercial irrigation. Dig Irrigation (digcorp.com) explored wireless valve controllers years ago, but the product never reached widespread market availability.

Practical Alternatives

• Wired flow control valve + wireless controller: Use a standard electric flow control valve (e.g., Rain Bird TBOS or Hunter ICV with flow control) paired with a battery-operated wireless controller like Hunter's Node or Rain Bird's TBOS system.
• Smart controller with flow sensor: Controllers like Rachio, Hydrawise, or RainMachine support wired flow sensors and remote app-based adjustment—no radio valve needed.
• Manual regulating valve: For set-and-forget applications, a simple inline pressure-regulating or needle valve adjusted once at installation often suffices.

True wireless proportional valves exist in industrial process control but are cost-prohibitive ($500+) for irrigation. For 100-foot range, a wired valve with a wireless controller is the most reliable, affordable solution.
