Introduction

These solenoid valves can be used to control the flow of liquid. They are equipped with three control wires: red, yellow and blue. connect the blue wire to positive pole to open the valve, or connect the red wire to positive pole to close the valve. The yellow wire is the shared ground line. Use the solenoid valve with the relay to open or close the valve at a predetermined time. This product is an automated and manual solenoid valve. When the valve is powered off, it will stop working and keep the current state, and then we can open or close the valve manually.

These solenoid water valves integrate valve and DC motor in one piece, inside of which has metal reduction gearbox with large torque, low noise and easy to install. We also use sealing design for the motor to make the entire structure more reliable. The valve features stable performance, high sensitivity and anti-electromagnetic interference. It can withstand 1.0Mpa static pressure. It can be widely used in smart home, automatic agriculture, fisheries and other projects that require the precise controlling of water flow

Tutorial

This tutorial will show you how to drive the solenoid valve to open or close through a relay under the control of UNO mainboard.

Requirements

Hardware

• DFRduino UNO R3 x 1
• Solenoid Valve DN15 x 1
• Gravity: Digital 5A Relay Module(Arduino Compatible) x 1
• PC x 1
• Dupont lines x n

Software

• Arduino IDE

Connection Diagram

• Pin definitions of the connecting terminal of the relay module:

• NC: normally closed terminal
• NO: normally open terminal
• N/A: not available
• COM: common terminal

• Connect the control terminal of the relay module to Arduino: green wire goes to the digital pin 3; red wire to 5V pin; black wire to GND;
• Connect the connecting terminal of the relay module to external power supply and solenoid valve: COM port goes to the positive pole of external power supply; NO port to red wire of the solenoid valve; NC port to blue wire of the valve;
• Connect the yellow wire of solenoid valve to the negative pole of the external power.

There is an open/close indicator on the solenoid valve: it displays | when the valve is closed, and — when the valve is open. The circle at the right-lower corner of the solenoid valve is an Off/On switch, pull it out gently and then we can close or open the valve manually.

Wiring Diagrams of CWX-25S mini motorized ball valve:

CR02 (three wires two wires control) Voltage: DC3-6V/DC9-24V

1. Connect SW to OPEN, the valve open, getting the position and automatically power off, the valve remains fully open position.
2. Connect SW to CLOSE, the valve close, getting the position and automatically power off, the valve remains fully closed position

Manual use of CWX-25S

Manual function can only be used in case of power failure (see the figure below)

1. Lift the handwheel and rotate it left and right until the valve is in place.
2. The handwheel must be pressed after manual operation so that the electric motor can be used normally.
