PAV 3-Way 1/2" to 1 1/2" Motorized Valve- 3 Wire- IP54-(Not Waterproof -Indoor use or in an Enclosure) - For Clean Water

Recommended usage for clean drinking water (potable water). If you use this valve for grey water, rain water, dam water and borehole water, make sure you have filtration of at least 20 microns before valve inlets.

This electric ball valve is a type of valve that uses an electric motor to control the opening and closing of the valve. The motor rotates the ball inside the valve, which controls the flow of fluid. This is NOT a Failsafe actuator. You control movement with 3 wires. One wire is common and you select the second wire to connect to power depending on the movement direction you need(Open or Closed).Usually the wire Green/Yellow is permanently connected (N-for 220VAC and 0Volt(Gnd) for DC). The other Polarity (L-220VAC or +12/24VDC) For the Movement Direction you then choose either Blue to OPEN or Brown to CLOSE. If you have a SONOFF device with only a Normal Open contact, you will need to select and buy the additional RELAY kit to connect in between the SONOFF and Valve Actuator for Direction change.(Blue to Brown) (When the power fails the Valve will stay where it is , unless you have wired a backup power source. Lately you get SONOFF devices with Changeover Relays built in with COM+NOpen+NClose contacts to operate this valve.
