Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed independently, improving and perfecting the structure of our mature products, optimizing the protective performance and key components. They feature compact design, small size, attractive appearance, and stable and reliable performance. The good protection grade meets various design requirements: 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 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's performance complies with the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and meets the specifications of 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: Intrinsically Safe "d"), and JB/T8529-1997 (Technical Conditions for Intrinsically Safe Electric Actuators).

Three: Adjust
Adjust the torque during travel; 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 switch 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 without medium pressure, etc. When there is pressure or temperature, attention should be paid to whether it can be sealed properly. If it cannot be sealed, the torque value should be appropriately increased to ensure it can be sealed and opened.
2. Travel control mechanism adjustment:
(1) Manually close the valve tightly.
(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 driven small gear 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 the initial adjustment of the OFF travel is complete.
（4）
At this point, you can turn it on electrically for a few rotations and then turn it off. 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 actuate. Reengage the stroke mechanism with the driving gear to complete the opening stroke adjustment. After adjusting the stroke control mechanism, the operation can be repeated several times. Generally, the valve opening is controlled around 90%.
3. Adjustment of the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after tuning the gear ratio and travel.
