I: Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed and improved upon our mature products, optimizing protection performance and key components. They are completely self-developed, featuring a compact structure, small size, attractive appearance, and stable and reliable performance. The good protection grade meets the needs of various designs: explosion-proof, overall switch type, and overall regulating type.
The DZW series is used for controlling the opening and closing of valves. Suitable for gate valves, stop valves, check valves, diaphragm valves, and its derivative products can be used for ball valves, butterfly valves, and air gates, etc. It can accurately respond to control commands, making it an indispensable drive device for remote control, centralized control, and automatic control of valves.
This product meets the specifications of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and the performance of explosion-proof types 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
Adjusting torque, while moving the stroke, ensure the potentiometer on the position indicator is disengaged (loosen the set screw on the gear of the potentiometer shaft to disengage) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the closing torque.
(2) Start from a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque of the switch direction based on the valve's operating characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no load and no medium pressure. When there is pressure and temperature, pay attention to whether it can be sealed properly. If it cannot be sealed properly, increase the torque value appropriately to ensure it can be sealed and opened easily.
2. Traveler control mechanism adjustment:
(1) Close the valve manually.
(2) Disengage the travel control mechanism by using a screwdriver to push the top rod in the travel control mechanism and rotate it 90°, thereby separating the driven small gear from the counter's unit gear set.
(3) Rotate the "Off" position using a screwdriver to the adjusting shaft, turning in the direction of the arrow until the cam presses against the spring plate, causing the microswitch to actuate. This indicates that the "Off" travel is initially adjusted.
（4）
At this point, you can electrically turn it a few rotations, then close it. Check if the closing stroke meets the requirements. If not, adjust it again following the aforementioned procedure.
(5) Direction Adjustment: After the valve is properly adjusted in the closed direction, 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 activate. Reengage the stroke mechanism with the driving gear, and the opening stroke is complete. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, the valve opening is controlled around 90%.
3. Adjustment of the adjustable opening indicator:
(1) Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
