Control open close with relay contacts or switch. Compatible with any system that supports relay contact control including most home security systems. Also supports open/close valve control with a wired switch. High torque and intelligent stroke control make Econet's Bulldog Valve Robot ideal for the toughest valves and installations. This smart valve controller kit fits most standard valves from ¾" to 1 ½" and automates water flow control, allowing you to remotely open or close your valves in seconds using the toggle switch included, or any alternative relay contact control connected to the 2.5mm stereo jack.
