Product Description

Product Description

RKF-4 is a shut-off motor valve and is compatible with various specifications of gas meters. It owns features, such as small body, low pressure loss, durability and reliability, explosion-proof performance, low power consumption, short switch time, etc. All our products have the ATEX explosion-proof citification and can customize based on customers' requirements.

Built-in screw Motor Valve's Advantages:
1. Low-pressure drop
2. Stable structure Max pressure can reach 150mbar
3. Small shape, easy to install
4. Low cost

Product Instruction:
1. This type of valve has two lead wires to supply power to the valve. The red wire is connected to positive power (or negative power), and the black wire is connected to negative power (or positive power) to open the valve (specifically, it can be set according to customer needs).

2. The minimum drive voltage of the valve shall not be lower than 3V. If the current limit design is in the process of opening and closing the valve, the current limit value shall not be lower than 130mA.

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.
