I. Overview
The DZW series electric actuators are our company's latest generation of products, which have been improved and refined on the basis of our mature products. They feature compact structure, small size, attractive appearance, and stable and reliable performance. The excellent protection level meets the requirements of various designs: explosion-proof, full switch type, and full adjustment 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 applied to ball valves, butterfly valves, and dampers, etc. It can accurately actuate according to control commands, and is 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 of General Valves) and the performance of explosion-proof types 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 the 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. 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 with a screwdriver around the adjustment shaft until the cam presses down on the spring plate, causing the microswitch to activate. This indicates that the initial OFF travel is properly adjusted.
（4）
At this point, you can electrically turn it a few rotations, then close it. Check if the closing stroke 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. Once the stroke mechanism engages with the driving gear, the opening stroke is complete. After adjusting the stroke control mechanism, it can be operated repeatedly. Generally, the valve is opened to about 90%.
3. Adjustment of the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the gear and travel.
