Online Exporter China 1 Inch Brass 12V 24V Electric Motor Small Ball Valve 2-Way for Smart Home Control

Model No.: RKF-6

Short Description:

This product is a special valve installed in a gas meter to control gas disconnection. The valve adopts gear transmission, which simplifies the structure and greatly improves the reliability and performance. This is a Full bore valve with patent special stucture, so it has good dust-proof performance and no pressure drop.

instruction for use

1. The lead wire of this type of valve has three specifications: two-wire, four-wire or six-wire. The lead wire of the two-wire valve is only used as the valve action power line, the red wire is connected to positive (or negative), and the black wire is connected to negative (or positive) to open the valve (specifically, it can be set according to customer needs). For four-wire and six-wire valves, two of the wires (red and black) are the power supply wires for valve action, and the remaining two or four wires are status switch wires, which are used as signal output wires for open and closed positions.
2. Four-wire or six-wire valve opening and closing process time setting: When the valve is opened or closed, when the detection device detects the signal of opening or closing the valve, the power supply needs to be delayed for 300ms, and then the power supply is stopped. The total valve opening time is about 6s .
3. The two-wire motor valve opening and closing can be judged by detecting the locked-rotor current in the circuit. The locked-rotor current value can be calculated according to the working cut-off voltage of the circuit design, which is only related to the voltage and resistance value.
4. It is recommended that the minimum DC voltage of the valve should not be less than 2.5V. If the current limit design is in the valve’s process of opening and closing, the current limit value should not be less than 60mA.
