I: Overview
DZW Series Electric Actuator for Valves is a new generation product that our company has improved and refined the structure based on our mature products, optimizing the protection performance and key components. It is a completely self-developed product featuring compact structure, small size, attractive appearance, and stable and reliable performance. Its good protection grade can meet various design requirements: explosion-proof, overall switching, 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 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 the explosion-proof performance 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 Type "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjust the torque while traveling. Ensure the potentiometer on the position indicator is disconnected (loosen the set screw on the gear of the potentiometer shaft) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the torque.
(2) Start from a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque of the on/off direction based on the valve's operating characteristics; typically, the torque for the open direction is greater than that for the close direction.
(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 properly, 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 travel control mechanism by using a screwdriver to push the top rod in the travel control mechanism and rotate it 90°, thereby separating the driven small gear from the counter's unit gear set.
(3) Rotate the "Off" position with a screwdriver towards the adjustment shaft, turning until the cam engages the spring plate, causing the microswitch to activate. This indicates that the "Off" stroke is initially adjusted.
（4）
At this point, you can electrically turn it a few rotations, 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 until the cam presses the spring plate, causing the microswitch to activate. Reengage the stroke mechanism with the driving gear for the opening stroke adjustment to be complete. After adjusting the stroke control mechanism, it can be operated repeatedly several times. Generally, the opening of the valve is controlled around 90%.
3. Adjustment of the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
