1.0 Mpa Zone Heating Valves 3 Wires 2 Points DN40 Water Flow Control

3 wires 2 points control zone heating valves, hot water flow control valves 95
℃



Product Description



Our heating zone control valves are available from DN15 to DN32, and many
different thread connection ports. This CW25S zone control valve has the manual
OPEN/CLOSE function in case of no electricity, lift the manual handle and turn
it on or off, and it will get heat when any of the other zones call for heat.
They can used for hot water flow controls, priority zoning circulators, or fan
controls, central heating and cooling systems.

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

Two wires and reverse polarity (DC3-6V / DC12V)
1.0 Mpa Zone Heating Valves 3 Wires 2 Points DN40 Water Flow Control 2

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)
1.0 Mpa Zone Heating Valves 3 Wires 2 Points DN40 Water Flow Control 3

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)
1.0 Mpa Zone Heating Valves 3 Wires 2 Points DN40 Water Flow Control 4

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)
1.0 Mpa Zone Heating Valves 3 Wires 2 Points DN40 Water Flow Control 5

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)
1.0 Mpa Zone Heating Valves 3 Wires 2 Points DN40 Water Flow Control 6

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".
