Built- in Motor Shut-off Valve for Business and Industrial Gas meter

Model No.: RKF-5

Short Description:

Model No.: Built- in Motor Shut-off Valve for Business and Industrial Gas meter
This product is a special valve installed in a gas meter to control gas disconnection. Adopting a unique shape design, it has high reliability, low pressure loss, and controllable cost. At the same time, we use the process of gold plating on the motor commutator, which greatly improves the corrosion resistance of the valve

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 requierements). For four-wire and six-wir e 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. Power supply time requirements: when opening/closing valve, after the detection device detects that the valve is in place, it needs to delay 2000ms before stopping the power supply, and the total operating time is about 4.5s.
3. The 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 3V. If the current limit design is in the valve’s process of opening and closing, the current limit value should not be less than 120mA.
