This motorized ball valve is useful for automating water flow in the heating circuits, water mains in low-rise buildings, pools, rain water collectors, auto-irrigation systems, or even leakage protection.
The device is based on a 1/2 inch brass ball valve for pipes. It maintains pressure up to ten atmospheres and water temperature up to 100 °C (212 °F). It is designed to work at 12 V and has built-in limit switches.
The valve servo is connected to the control electronics via three wires:
It would be easy and convenient to use these devices with a Troyka relay.
Normally closed contacts of the relay will correspond to the open position of the valve, whereas a normally open connection will correspond to a closed valve.
Once you activate the relay, the valve will open in three seconds, the limit switches will engage, the motor will turn off. After moving the valve, the module does not consume energy until the next relay operation.
