I. Overview
The DZW series electric actuators for valves are a new generation of products developed by our company, which are improved and optimized based on our existing mature products. They feature a compact structure, small size, aesthetically pleasing design, and stable, reliable performance. The excellent protection level meets the needs of various designs, including explosion-proof, full-featured on/off, and full-featured regulating types.
The DZW series is used for controlling the opening and closing of valves. It is suitable for gate valves, stop valves, check valves, diaphragm valves, and 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 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 the explosion-proof type meets the standards 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: Explosion-Proof Type "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjust the torque, while in motion, 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 the valve's operational characteristics; typically, the open direction torque is greater than the close direction torque.
(4) Adjustments are made under conditions of no-load and 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. Traveler 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 until the cam engages the spring plate, following the arrow direction until the microswitch actuates. This indicates the initial adjustment of the "OFF" travel is complete.
（4）
At this point, turn a few circles electrically, then close it. Check if the closing stroke meets the requirements; if not, adjust it again following the aforementioned procedure.
(5) Adjustment of Opening Direction: After the closing 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 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 opening of the valve is controlled around 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
