China OEM Stainless Steel Female Thread BSPT 2PC Ball Valve

Model No.: RKF-2

Short Description:

Model No.: RKF-2 Built -in Fast-close Motor Valve for Smart Gas meter
This product is a special valve installed in a gas meter to control gas disconnection. Adopting a unique ratchet mechanism design, there is no motor blocking problem in the process of opening and closing the valve. This design prevents gears from being damaged or jammed under high voltage. There is a spring in the valve, which absorbs energy when the valve is opening, so the energy required to close the valve is extremely low, which can achieve instantaneous closing 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 requirements: DC2.5V for 2s when opening valve. When the valve is closing, the power supply time should be longer than 300ms, and the valve can be effectively opened and closed.
3. The minimum drive voltage of the valve shall not be lower than 2.5V. If the current limit design is in the process of opening and closing the valve, the current limit value shall not be lower than 100mA
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.
