I: Overview
The DZW series electric actuators are a new generation product that our company has developed through improvements and optimizations to our existing mature products. They feature a compact structure, small size, attractive appearance, and stable and reliable performance. With a good protection rating, they can meet the needs of various designs, including explosion-proof, overall switching, and overall regulating types.
The DZW series is designed for controlling the opening and closing of valves. Suitable for gate valves, stop valves, check valves, diaphragm valves, and its derivatives can be used for ball valves, butterfly valves, and air gates, etc. It can accurately operate according to control commands, making it an indispensable driving device for remote control, centralized control, and automatic control of valves.
This product meets the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators for Valves of General Type). The explosion-proof type performance conforms to GB3836.1-2000 (Part 1 of Electrical Equipment for Explosive Gas Atmospheres: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Atmospheres: Explosion-Proof Type "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjust the torque while traversing. Ensure the potentiometer on the position indicator is disconnected (loosen the set screw on the potentiometer shaft's gear) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the torque.
(2) Begin with a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque for switching direction based on the valve's operational characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no load, no medium pressure, etc. When there is pressure and temperature, attention should be paid to whether it can be tightly sealed. If it cannot be sealed tightly, the torque value should be appropriately increased to ensure it can be tightly sealed and easily opened.
2. Travel Control Mechanism Adjustment
(1) Close the valve manually.
(2) Disengage the stroke control mechanism by using a screwdriver to push the top rod in the stroke control mechanism and rotate it 90°, thereby separating the driving small gear from the individual gear set of the counter.
(3) Rotate the screwdriver to adjust the "OFF" direction until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the initial adjustment for the "OFF" direction is complete.
（4）
At this point, you can electrically turn it a few rotations, then shut it off. Check if the closing stroke meets the requirements; if not, adjust it again following the aforementioned procedure.
(5) Adjustment of Opening Direction: After the closing direction is adjusted, manually open the valve to the desired position. Then disengage the stroke control mechanism, rotate the "open" adjustment shaft in the direction of the arrow until the cam presses against the spring plate, causing the microswitch to actuate. Reengage the stroke mechanism with the driving gear to complete the opening stroke adjustment. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, the opening of the valve is controlled around 90%.
3. Adjustable Opening Indicator Adjustment:
(1) Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
