I: Overview
The DZW series electric actuators are an improved and refined version of our company's mature products, featuring optimized protection performance and key components, and are our fully自主研发 new generation products. They offer advantages such as compact structure, small size, aesthetic appearance, and stable and reliable performance. The good protection grade meets the needs of various designs: explosion-proof, full switching, and full regulating types.
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 respond to control commands, and is an indispensable driving device for remote control, centralized control, and automatic control of valves.
This product meets the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and has explosion-proof performance in compliance with 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 "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 disconnected (loosen the set screw on the gear of the potentiometer shaft to disconnect) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the closing 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 operating characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no-load and without medium pressure. When there is pressure and 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 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 pinion from the counter's unit gear set.
(3) Rotate the screwdriver to turn the "OFF" adjustment shaft in the direction of the arrow until the cam engages the spring plate, causing the micro-switch to activate. This indicates that the "OFF" travel is initially adjusted.
（4）
At this point, turn the switch a few times electrically, then turn it off. Check if the closing stroke meets the requirements; if not, adjust again according to the above procedure.
(5) Adjustment of the Opening Direction: After adjusting the closing 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 and the microswitch actuates. Once the microswitch actuates, engage the stroke mechanism with the driving gear, and the opening stroke is complete. After adjusting the stroke control mechanism, you can repeat the operation several times. Generally, the opening of the valve is controlled around 90%.
Adjustment of the adjustable opening indicator:
(1) Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
