Electric centerline flange butterfly valve

Electric butterfly valve is matched by butterfly valve and electric actuator mechanism. It can be controlled by switch type (active or passive feedback signal can be provided) or adjustable input control signal (4～20mA or 0～10VDC) and single-phase power supply. Electric butterfly valve has strong function, small size, light weight, reliable performance, simple matching, large flow capacity, electric butterfly valve is especially suitable for occasions where the medium is viscous, contains particles, and fiber. 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.

产品介绍

Parameters

1. Product overview

2. Product performance characteristics

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

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 handwheel 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 mirror design, which does not accumulate water and is convenient for observation.

5. Dryer: It can prevent moisture condensation inside the actuator 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: Adopting precise double worm gear mechanism, high transmission efficiency, large torque, high efficiency, low noise (maximum 50 decibels), preventing reverse rotation, the transmission part is stable and reliable, no need to refuel.
