GDF-4 Motor Pipeline Stop Valve for Gas Flow Meter

Model No.: GDF-4

Short Description:

GDF-4 pipeline shut-off valve is a valve used on gas pipelines to control the on-off of the transmission medium. It can be installed on the gas pipeline as an independent component, and can automatically control the on-off of gas reliably; it can also be used in conjunction with a flow meter to realize the functional integration of pipeline gas metering and on-off control.

Product Features

1. It is a slow-opening and fast-closing valve, and the closing time is ≤2s;

2. Wide range of working pressure, the maximum working pressure can reach 0.8MPa;

3. Small pressure loss;

4. Good sealing, stable and reliable performance;

5. The special structure design of valve opening and pressure relief can realize the valve opening with low load and low power consumption in high pressure environment, which enhances the reliability of valve operation;

6. The valve body is made of cast aluminum alloy, which is light in weight and good in corrosion resistance, and can withstand a nominal pressure of 1.6MPa; the overall structure is resistant to impact, vibration, high and low temperature, salt spray, etc., and can adapt to various complex outdoor environments;

7. The motor and gearbox are designed as a fully sealed structure, the protection level is ≥ IP65, and the motor and gearbox have no contact with the transmission medium, and the explosion-proof performance is good. Greatly improved valve reliability and service life;

8. The executive mechanism is strong, and it can be blocked directly after the opening and closing are in place, and can also be brought to the position switch;

9. After the valve is opened and closed in place, the movement mechanism is automatically locked to ensure that the valve will not malfunction due to external force when it is in a stable state;

10. The micro-motor is finely processed, the commutator is gold-plated, and the brushes are made of precious metals, which greatly improves the corrosion resistance and stability of the micro-motor itself, ensuring the long-term reliable operation of the motor valve;

11. The air intake direction can be adjusted.
