I: Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed through improvements and optimizations on our existing mature products. They feature a compact structure, small size, aesthetically pleasing design, and stable, reliable performance. Their excellent protection grade meets the needs of various designs: explosion-proof, overall on/off, and overall 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 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 meets the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and 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: Flameproof Type "d"), as well as JB/T8529-1997 (Technical Conditions for Flameproof 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 direction for valve operation characteristics; typically, the open direction torque is greater than the close direction torque.
(4) Adjustments above are made under conditions of no load, no medium pressure, etc. When there is pressure and temperature, attention should be paid 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 pinion from the counter's unit gear set.
(3) Rotate the "OFF" position with a screwdriver to the adjusting shaft, turning until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the initial OFF travel has been properly adjusted.
（4）
Now, turn it on electrically a few turns, then turn it off. Check if the closing travel meets the requirements; if not, adjust it again following the above procedure.
(5) Direction Adjustment: After the closed direction is adjusted, 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 to complete the opening stroke adjustment. After adjusting the stroke control mechanism, you can repeat the operation a few times. Generally, the valve opening is controlled around 90%.
3. Adjustable opening indicator adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
