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 various design requirements: 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 dampers, etc. It can accurately actuate according to control commands, and is 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 meets the specifications of GB3836.1-2000 (Part 1 of Electrical Equipment for Explosive Gas Environment: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Environment: Explosion-Proof Type "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjust the torque, during travel, 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) Begin with a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque of the on/off direction based on the valve's operational characteristics; typically, the torque for the open direction is greater than that for the close direction.
(4) Adjustments are made under conditions of no load, no medium pressure, etc. When there is pressure or temperature, attention should be given to whether it can be sealed properly. If it cannot be sealed properly, the torque value should be appropriately increased to ensure it can be sealed and opened.
2. Travel control mechanism adjustment:
(1) Manually close the valve tightly.
(2) Disengage the stroke control mechanism by using a screwdriver to push the top rod in the stroke control mechanism and rotate it 90°, thus separating the driving pinion from the counter's unit gear set.
(3) Rotate the "Off" adjustment shaft with a screwdriver until the cam engages the spring plate, following the arrow direction until the microswitch action is achieved. The "Off" stroke 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) Valve Opening Adjustment: After the closing direction adjustment is complete, 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 engages the spring plate, causing the micro-switch to activate. Reengage the stroke mechanism with the driving gear to complete the opening stroke adjustment. After adjusting the stroke control mechanism, the operation can be repeated several 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 gear and travel.
