I. Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed and improved upon our existing 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 products are used to control the opening and closing of valves. Suitable for gate valves, stop valves, throttle valves, diaphragm valves, and their derivatives can be used for ball valves, butterfly valves, and wind gates, etc. They can accurately respond to control commands, making them an indispensable driving device for remote control, centralized control, and automatic control of valves.
This product's performance meets the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators for Valves of General Type). The explosion-proof model's performance complies with GB3836.1-2000 (Part 1: General Requirements for Electrical Equipment Used in Explosive Gas Atmospheres), GB3836.2-2000 (Part 2: Explosion-proof Type "d" for Electrical Equipment Used in Explosive Gas Atmospheres), 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 disengaged (loosen the set screw on the gear of the potentiometer shaft) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the closing torque.
(2) Begin with a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque for the switch 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, without medium pressure, and other factors. 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 tightly sealed and easily opened.
2. Travel 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 driving sprocket from the counter's unit gear set.
(3) Rotate the "Off" screwdriver towards the adjustment shaft, and continue to turn in the direction of the arrow until the cam presses against the spring pressure plate, at which point the micro-switch action is achieved. The "Off" travel is then 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 closed direction adjustment is complete, manually open the valve to the desired position. Then disengage the stroke control mechanism, rotate the "open" adjustment shaft until the cam presses the spring plate, causing the microswitch to activate. Reengage the stroke mechanism with the driving gear for the adjustment to be complete. After adjusting the stroke control mechanism, the operation can be repeated a few times. Generally, the valve is opened to about 90%.
Adjustment of the adjustable opening indicator:
(1) Adjust the adjustable opening indicator and remote potentiometer after adjusting the gear ratio and stroke.
