Electric zone heating valves, auto heater control valve by brass ball valve with actuator
Product Description
Typically, the heating systems with zone valves, will be installed with two or more zone valves (usually but not always located close to the heating boiler) and a single circulator pump (usually located on the return end of the hot water piping close to the heating boiler).
Features
1. Extreme long service life span ;
2. Manual Override, the valve can be operated when power failure;
3. Mini dimension and position indicator
4. Good sealing performance, IP65 enclosure

Wiring options
1. Connecting SW to OPEN , the valve opens , getting the position ,automatically power off, the valve remain fully open position
2. Connection SW to CLOSE , the valve close , getting the position ,automatically power off, the valve remains side passes position(fully closed)
1. Connecting SW to OPEN, the valve opens , getting the position ,automatically power off, the valve remain fully open position
2. Connection SW to CLOSED, the valve close , getting the position ,automatically power off, the valve remains side passes position (fully closed)
Note: AC24V/AC220V can only be used for 50K series electric valves
1.Connecting SW, the valve opens , getting the position ,automatically power off, thevalve remain fully open position
2.Disconnecting SW, the valve close , getting the position ,automatically power off, the valve remains side passes position (fully closed)
Note:When power is DC voltage and Red Wires is “+”,Blue wire is “—”
1. SW connecting, the valve open, getting the position and the power off automatically, the valve remains fully open/close position
2. SW disconnecting, the valve close, getting the position and power off automatically, the valve remains fully open/close position
1. Connecting SW and OPEN, the valve opens, getting the position green wire output the OLS signal, the controller tests the signal OLS, connect SW to STOP, the valve stops and remains fully open position
2. Connecting SW and CLOSE, the valve close, getting the position red wire output the CLS signal, the controller tests the signal CLS, connect SW to STOP, the valve stops and remains fully close position,
Note: Please make sure the signal wires "red", "black" and "green" be connected at first, then connect the power wires " yellow" and "blue".
