I: Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed and refined based on our mature products, optimizing protection performance and key components. They are entirely self-developed, featuring compact structure, small size, attractive appearance, and stable and reliable performance. With a good protection rating, they can meet the needs of various designs: explosion-proof, full-on/full-off, and full-range adjustment.
The DZW series is used to control the opening and closing of valves. Suitable for gate valves, stop valves, check valves, diaphragm valves, and its derivatives can be used for ball valves, butterfly valves, and air doors, etc. It can accurately respond to control commands and is 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
Adjusting torque, during travel, it is mandatory to check if the potentiometer on the position indicator has been disconnected (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) 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, 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. Traveler 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 sprocket from the counter's unit gear set.
(3) Rotate the "OFF" position adjustment shaft with a screwdriver in the direction of the arrow until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the "OFF" position travel has been initially adjusted.
（4）
At this point, turn the electrically powered device a few rotations and then shut it off. Check if the closing travel meets the requirements; if not, adjust according to 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 micro-switch to activate. Once the stroke mechanism engages with the driving gear, the opening stroke 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 adjusting the gear ratio and travel.
