Underfloor Heating Systems Intelligent Zone Heating Valves 3 Way IP65 Protection

Intelligent zone heating valves, 3 way heating valves for underfloor heating systems

 

Product Description

 

The heating control zone valves, are consisted of: mini motorized ball valve and electric actuator motor. It includes auxiliary limit switches to determine if the valve is completely open or closed. These systems use these signals to control a pump (circulator) and boiler to start pumping the hot water. The water then flows through the system, heating the zone, until the respective thermostat’s temperature setting is reached.

 

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

 

Application

Advantages

• Sturday valve body with reasonable structure design, and best material to be used

No.	Ours	Normal products

Wiring options

• Two wires and reverse polarity (DC3-6V / DC12V)

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)

• Three wires and two control points (DC3-6V / DC12V / DC24V)

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

• Three wires and one control point (DC3-6V/12V)

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 “—”

• Two wires and power off return (DC3-6V/ADC9-24V/AC220V)

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

• Five wires micro conntroller with signal feedback (DC3-6V/12V)

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".
