I: Overview
The DZW series valve electric actuators 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 completely self-developed, featuring compact structure, small size, attractive appearance, and stable and reliable performance. The good protection level meets the needs of various designs: explosion-proof, overall switch type, and overall regulating type.
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 air gates, etc. They can accurately operate according to control commands and are an indispensable driving device for remote, centralized, and automatic control of valves.
This product meets the specifications of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and the performance of explosion-proof type conforms 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 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 torque for switching direction based on the valve's operational characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments are made under conditions of no load and 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. 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 driving small gear from the counter's unit gear set.
(3) Rotate the "OFF" position using a screwdriver to the adjustment shaft, turning until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the initial "OFF" travel is properly adjusted.
（4）
At this point, you can turn the switch a few times electrically, then turn it off. Check if the closing stroke meets the requirements. If not, adjust it again following the above 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 engages the spring plate, causing the microswitch to activate. Once the stroke mechanism engages with the driving gear, the opening stroke adjustment is complete. After adjusting the stroke control mechanism, the operation can be repeated several times. Generally, the valve is opened to about 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
