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 the protective 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, shutoff valves, diaphragm valves, its derivative products can be applied to ball valves, butterfly valves, and dampers, etc. It can accurately actuate according to control commands, and is an indispensable driving device for remote, centralized, and automatic control of valves.
This product's performance meets the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and is explosion-proof, conforming 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 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 torque.
(2) Start 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; generally, the torque for the opening direction is larger than that for the closing direction.
(4) Adjustments are made under conditions of no load, no medium pressure, etc. When there is pressure and temperature, attention should be given to whether it can be sealed properly. If it cannot be sealed, the torque value should be appropriately increased to ensure it can be sealed and opened easily.
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 driven small gear from the counter's unit gear set.
(3) Rotate the "Off" position using a screwdriver until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the initial adjustment of the "Off" travel is complete.
（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 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 adjustment is complete. 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 ratio and travel.
