I: Overview
The DZW series electric actuators for valves are our company's new generation products, improved and perfected on the basis of our mature products, featuring optimized protection performance and key components, all independently developed. They offer compact structure, small size, attractive appearance, and stable, reliable performance. The excellent protection rating meets the needs of various designs: explosion-proof, overall switching, and overall regulating types.
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 air doors, 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 requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and the performance of explosion-proof types 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
Adjusting torque, during travel, it is essential to check if the potentiometer on the position indicator has been disconnected (simply loosen the set screw on the gear of the potentiometer shaft to disconnect it) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the torque.
(2) Start from 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 operating 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 and temperature, attention should be given to whether it can be tightly sealed. If it cannot be sealed tightly, the torque value should be appropriately increased to ensure it can be tightly sealed and easily opened.
2. Cruise 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 pinion from the counter's unit gear set.
(3) Rotate the "OFF" adjustment shaft with a screwdriver in the direction of the arrow until the cam engages the spring plate, causing the microswitch to activate. This indicates that the initial "OFF" travel has been properly adjusted.
（4）
At this point, you can turn the switch a few times electrically, then turn it off. Check if the closing travel meets the requirements. If not, adjust according to 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 in the direction of the arrow until the cam presses against the spring plate, causing the micro-switch to activate. Once the stroke mechanism engages with the driving gear, the opening stroke is adjusted. After adjusting the stroke control mechanism, it can be operated repeatedly. Generally, the valve is opened to about 90%.
3. Adjustable Opening Indicator Adjustment:
(1) Adjust the adjustable opening indicator and remote potentiometer after adjusting the gear shift and stroke.
