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 protection 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 the needs of various designs: 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, check valves, diaphragm valves, its derivative products can be used for ball valves, butterfly valves, and dampers, etc. It can accurately actuate according to control commands, making it an indispensable drive 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 Type Valves) and the performance of explosion-proof types conforms to GB3836.1-2000 (Part 1 of Electrical Equipment for Explosive Gas Environments: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Environments: Explosion-Proof "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjust the torque while moving, 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) Start from 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 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" 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 initial OFF position travel is properly adjusted.
（4）
Now, turn it on electrically a few times, then turn it off. Check if the closing travel 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 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:
(1) Adjust the adjustable opening indicator and remote potentiometer after tuning the gear ratio and stroke.
