An Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed through improvements and optimizations on our existing mature products. They feature a compact structure, small size, attractive appearance, and stable and reliable performance. The good protection level meets the needs of various designs: explosion-proof, all-position switch, and all-position regulating.
The DZW series is used for controlling the opening and closing of valves. Suitable for gate valves, stop valves, shutoff 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 driving 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 for Valves of General Type) and the performance of explosion-proof type complies with 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 disengaged (loosen the set screw on the gear of the potentiometer shaft) 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 switching direction torque of the valve based on its operational characteristics; generally, the opening direction torque is larger than the closing direction torque.
(4) Adjustments are made under conditions of no load, without medium pressure, etc. When there is pressure and temperature, attention should be given to whether it can be tightly closed. If it cannot be tightly closed, the torque value should be appropriately increased to ensure it can be tightly closed and easily opened.
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 screwdriver towards the adjustment shaft, turning until the cam presses against the spring plate, causing the microswitch to activate. This indicates the initial adjustment of the "Off" position is complete.
（4）
At this point, you can electrically turn it a few rotations and then shut it off. Check if the travel direction meets the requirements; if not, adjust it again following the above procedure.
(5) Direction Adjustment: After the closure direction is adjusted, 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 actuate. Once the stroke mechanism engages with the driving gear, the opening stroke adjustment is complete. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, the valve is opened to about 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after tuning the gear ratio and travel.
