ONE. Product Overview

Electric butterfly valve is made of butterfly valve and electric actuator supporting mechanism, separate off type (can provide active or passive feedback signal) or control type input control signal (4 ~ 20mA or 0 ~ 10VDC) and single-phase power supply can control operation, electric butterfly valve has strong function, small size, light, Reliable performance, simple matching, large circulation capacity, electric butterfly valve is especially suitable for the medium is thick, containing particles, fiber properties of the occasion. At present, the electric regulating butterfly valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, power and other industries in the industrial automatic control system.

Two. product performance characteristics

1. Actuator shell: the shell is made of hard aluminum alloy, anodized and coated with polyester powder, with strong corrosion resistance and IP67 protection grade.

2, motor: fully enclosed squirrel cage motor, small volume, large torque, small inertia force, insulation grade F, built-in thermal protection switch, can prevent damage to the motor.

3, manual structure: the design of the handwheel to ensure safe and reliable, labor-saving, small volume. When the power is off, the clutch handle can be manually operated.

4, indicator: the indicator is installed on the central axis, convex mirror design, no water, easy to observe.

5, dryer: can prevent moisture condensation due to temperature and weather changes in the actuator, keep the internal electrical components dry.

6, limit switch: mechanical, electronic double limit. Rotating screw can adjust the mechanical limit, safe and reliable; CAM mechanism to control electronic limit switch, adjustment mechanism adjustment simple, accurate positioning.

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

8, self-locking: precision worm gear and worm mechanism, high transmission efficiency, large torque, high efficiency, low noise (maximum 50 dB), prevent inversion, transmission part is stable and reliable, no need to refuel.
