Operating Instructions

1.This valve is four wires valve, of which when green wire is for opening valve that connects to "-" pole and closing valve that connects to "+" pole; when grey wire is for opening valve that connects to "+" pole and closing valve that connects to "-" pole. Another two yellow wires connect to power switches

2.Valve opening process is that when green wire connects "-" pole and gray wire connects "+" pole. And when detected the status of closing, then stop power supply after some time delay (not less than 100ms). The total time for opening valve is 3s.

3.Valve closing process is that when green wire connects "+" pole and gray wire connects "-" pole. After supplied power to motor for 200ms , then detecting if the signal switch is closing. If it is off, then stop to supply power to motor; if it is not off, then supply power to switch off. And the total time for closing valve is 300ms.

4.The voltage of valve both ends shall be 2.5~5.5V when valve is operating.

5.The driving current of valve control circuit provided can not be less than the motor peak current.

6.If the parameters and structure of this internal valve changes, our company will promptly inform your company.
