2. A powerful electric motor designed based on the working characteristics of valves, with high starting torque, low starting current, and small turning inertia. The stator winding assembly is equipped with a built-in overheat protector (automatic recovery type). When the valve accidentally gets stuck, the protector will control the motor to stop and protect the safety of the entire equipment.

3. Precision gears are composed of multiple gears and shafts that are precisely tangent to each other. The gears and shafts are made of heat-treated high alloy steel, which has high strength, good resistance, and can withstand long-term fatigue load impact. Add molybdenum based grease to the gear mechanism to achieve permanent lubrication without the need for inspection or maintenance.

4. The mechanical limit device, stainless steel made mechanical travel limit bolts, and limit blocks can accurately adjust the travel mechanism to the desired angle. For the convenience of adjustment, this bolt is placed on the outside of the housing and locked in the desired position with a stainless steel nut after each adjustment.

5. The valve opening display lens and the body are bonded with glass glue, with a strong bonding height, making the product pollution-free, heat-resistant, and effectively resistant to corrosion from harsh environments such as rainwater and bubbles.

6. The manual handle can use a stainless steel handle to drive the valve to rotate during debugging or power-off, with S being clockwise and O being counterclockwise.

7. The cable interface is equipped with two G1/2 waterproof cable joints, which are used for cable and signal lines respectively to prevent interference.

8. The HD series of micro switches uses imported micro switches, which have excellent and reliable indicators such as contact quality, action life, and insulation performance.

9. The precision potentiometer adopts high-precision potentiometer, with a service life of up to 30000 times! Very suitable for small opening adjustment of valves! Effectively ensure the precision adjustment of electric valves.

10. Control modules encapsulated in resin have significant characteristics such as high decomposition, strong functionality, vibration resistance, long lifespan, and reliability.

11. ServeThe built-in control module of the server continuously compares the input signal with the feedback signal of the potentiometer. When the balance is reached, the motor stops working, and then the output shaft keeps the valve in the corresponding position until the input signal changes. Ensure precise and continuous adjustment of valve opening

12. The automatic control intelligent integrated device has signal 4-20mA · DC input and output capabilitiescauseComputer PLC and DCS system control, proportional adjustment control and positioning, no need for manual control, canPosition self-locking、Simple connection, stable and reliable performance, high control accuracy, and fast response speedWait.

13. Easy installation，Easy connection.

14. Normally single-phase220V voltage, special supply availableDC220V、DC24、AC110VThree specifications
