D943W Electric Explosion-Proof Butterfly ValveIt is a set with butterfly valve and electric explosion-proof actuator mechanism, inputting control signals4～20mAOr1～5VDCThe unit can be controlled with a single-phase power source. Electric butterfly valves are characterized by their strong functionality, compact size, light weight, reliable performance, simple matching, and high flow capacity. They are particularly suitable for applications involving media that are thick, contain particles, or have fibrous properties. Currently, these electrically adjustable butterfly valves are widely used in industrial automatic control systems across various industries, including food, environmental protection, light industry, petrochemicals, papermaking, chemicals, educational and scientific equipment, and electricity.

D943WElectrical Explosion-Proof Butterfly ValveProduct Features：

1、Housing: The housing is made of hard anodized aluminum alloy with polyester powder coating, offering excellent corrosion resistance and a protective rating ofIP67。
2、Motor: Totally enclosed squirrel cage motor, compact in size, high torque, low inertial force, insulation grade:FGrade, with built-in thermal protection switch to prevent motor damage.
3、Manual Structure: The design of the handwheel ensures safety, reliability, ease of use, and compact size. Manual operation can be performed by actuating the clutch handle when power is off.
4、Indicators: The indicators are mounted on the center shaft, featuring a convex mirror design, non-accumulating water, and easy observation.
5、Dehumidifier: Prevents condensation inside the actuator due to temperature and weather changes, maintaining the dryness of internal electrical components.
6、Limit switches: Mechanical and electronic dual limiting. Adjusting the rotating screw allows for easy mechanical limiting, ensuring safety and reliability; a cam mechanism controls the electronic limit switch, with a simple adjusting mechanism for precise positioning.
7、Torque switch: Provides overload protection to prevent motor damage.
8、Self-locking: Utilizes precise double worm and worm gear mechanism, for efficient transmission, high torque, high efficiency, and low noise.), Prevents reversal, transmission part is stable and reliable, no need for additional oiling.
9、Screw Gear: Designed with a concave gear pattern to ensure a large contact surface with the worm shaft, providing high torque transmission, balance, wear resistance, and a long service life. Of course, the actuation and connection methods of this ball valve are not limited to the screw gear; they also include flanged and manual types.
