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 entirely 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 on/off, and overall regulating types.
The DZW series is used to control the opening and closing of valves. Suitable for gate valves, stop valves, throttle valves, diaphragm valves, its derivative products can also be used for ball valves, butterfly valves, and dampers, etc. It can accurately respond to control commands, making it an indispensable drive device for remote, centralized, and automatic control of valves.
This product's performance complies with the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators of Valves of General Type) and meets the specifications of 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 during travel, and ensure the potentiometer on the position indicator is disconnected (loosen the set screw on the gear of the potentiometer shaft to disconnect) 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 switch direction based on the valve's operating characteristics; generally, the opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no load, without medium pressure, etc. When there is pressure and temperature, pay attention to whether it can be sealed tightly. If it cannot be sealed properly, increase the torque value appropriately to ensure it can be sealed tightly and easily opened.
2. Traveler control mechanism adjustment:
(1) Close the valve manually.
(2) Remove the travel control mechanism by using a screwdriver to push the plunger in the travel control mechanism and rotate it 90°, thereby separating the driven small gear from the counter's single-digit gear set.
(3) Rotate the "OFF" adjustment shaft with a screwdriver in the direction of the arrow until the cam presses against the spring plate, stopping the microswitch action. This indicates the initial adjustment of the "OFF" travel is complete.
（4）
At this point, you can turn the switch a few times electrically, then turn it off. Check if the closing stroke meets the requirements; if not, adjust it again following the above procedure.
(5) Direction Adjustment: After the valve is 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, control the valve opening to about 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and travel.
