I: Overview
The DZW series electric actuators for valves are a new generation of products, developed and refined by our company based on our mature products. They feature a compact structure, small size, attractive appearance, and stable and reliable performance. Their excellent protection level meets various design requirements: explosion-proof, overall switch type, and overall regulating type.
The DZW series is used to control the opening and closing of valves. Suitable for gate valves, stop valves, check valves, diaphragm valves, and its derivative products are applicable to 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 specifications of JB/T8528-1997 (Technical Conditions for Electric Actuators of General Valves) and the performance of explosion-proof types complies 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 Type "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjusting 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 completely closed.
(3) Adjust the torque for switch direction based on the valve's operating characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments are made under conditions of no load, no medium pressure, etc. When there is pressure and temperature, attention should be given 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. Traveling 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 towards the adjustment shaft, turning until the cam presses the spring plate, causing the microswitch to activate. This indicates that the "Off" stroke 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 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 activate. Reengage the stroke mechanism with the driving gear, and the opening stroke is complete. After adjusting the stroke control mechanism, the operation can be repeated several times. Generally, the valve is opened to about 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and travel.
