    Product Name:D943W Type Explosion-Proof Electric Butterfly Valve
    Product Tag:Explosion-Proof Electric Butterfly Valves
    Update Date:2021/8/21 22:52:17

    Note: Our Products Can Be Customized According To Customers' Needs. In Addition To National Standards,We Can Design And Manufacture According To American Standards, Japanese Standards, German Standards, Russian Standards, British Standards And So On.

    D943W electric explosion-proof butterfly valve is matched by butterfly valve and electric explosion-proof actuator mechanism. Input control signal (4~20mA or 1~5VDC) and single-phase power supply can control operation. Electric butterfly valve has strong function, small size, light weight, reliable performance, The matching is simple, the flow capacity is large, and the electric butterfly valve is especially suitable for the occasions where the medium is viscous, contains particles, and fiber properties. At present, the electric regulating butterfly valve is widely used in the industrial automatic control system of food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and scientific research equipment, electric power and other industries.

    Product features of D943W electric explosion-proof butterfly valve:

    1. Shell: The shell is made of hard aluminum alloy, with anodized treatment and polyester powder coating, with strong corrosion resistance, and the protection level is IP67.

    2. Motor: fully enclosed squirrel cage motor, small size, large torque, small inertia, insulation class F, built-in thermal protection switch to prevent damage to the motor.

    3. Manual structure: The design of the hand wheel ensures safety, reliability, labor saving, and small size. When the power is off, the clutch handle can be operated manually.

    4. Indicator: The indicator is installed on the central axis and adopts a protruding lens design, which does not accumulate water and is easy to observe.

    5. Dryer: It can prevent the moisture inside the actuator from condensing due to changes in temperature and weather, and keep the internal electrical components dry.

    6. Limit switch: mechanical and electronic dual limit. The mechanical limit can be adjusted by rotating the screw, which is safe and reliable; the cam mechanism controls the electronic limit switch, the adjustment mechanism is simple to adjust and the positioning is accurate.

    7. Torque switch: can provide overload protection to prevent damage to the motor.

    8. Self-locking: adopts precise double worm gear mechanism, high transmission efficiency, large torque, high efficiency, low noise (maximum 50 decibels), prevents reverse rotation, the transmission part is stable and reliable, no need to refuel.

    9. Worm gear: The concave wheel design ensures a large contact surface with the worm, large transmission torque, balance and wear resistance, and long life. Of course, the driving mode and connection mode of this ball valve are not only limited to worm gear, but also flange type, manual type and so on.
