Overview
The DZW series electric actuators are a new generation of products that our company has developed independently, based on our mature products. We have improved and optimized their structure, protective performance, and key components. They feature a compact design, small size, attractive appearance, and stable, reliable performance. The good protection level meets various design requirements: explosion-proof, overall on-off 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 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 Environments: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Environments: Explosion-proof "d"), and JB/T8529-1997 (Technical Conditions for Explosion-proof 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 disengage) 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 no-load and medium-free pressure conditions, etc. When pressure and temperature are present, pay attention to whether it can be sealed properly. If it cannot be sealed properly, increase the torque value appropriately, ensuring 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 pinion from the counter's unit gear set.
(3) Rotate the "OFF" position using a screwdriver to the adjustment shaft, turning according to the arrow direction until the cam presses against the spring plate, stopping the microswitch movement. This indicates that the "OFF" travel is initially adjusted.
（4）
At this point, you can turn the switch a few times electrically, then turn it off. Check if the closing stroke meets the requirements. If not, adjust it again following the above 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 activate. 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%.
Adjustment of the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and travel.
