I. Overview
The DZW series electric actuators for valves are our company's new generation products, improved and refined on the basis of our mature products. They feature compact structure, small size, attractive appearance, and stable and reliable performance. The good protection level meets various design requirements: explosion-proof, full-on/full-off, and full-range regulating.
The DZW series is used for controlling the opening and closing of valves. Suitable for gate valves, stop valves, shutoff valves, diaphragm valves, and its derivative products can be used for ball valves, butterfly valves, and wind gates, 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 for Valves of General Type) and the performance of explosion-proof type conforms to 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 during travel and ensure the potentiometer on the position indicator is disconnected (loosen the set screw on the gear of the potentiometer shaft to disconnect) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the closing torque.
(2) Begin with a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque for switching direction based on the valve's operational 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 given to whether it can be sealed properly. If it cannot be sealed properly, the torque value should be appropriately increased to ensure it can be sealed and opened easily.
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 driven small gear from the counter's unit gear set.
(3) Rotate the "OFF" position adjustment shaft with a screwdriver, turning in the direction of the arrow until the cam presses against the spring plate, causing the microswitch to actuate. This indicates that the initial OFF position travel is properly adjusted.
（4）
Now, turn the electric switch a few rotations, then turn it off. Check if the closing travel meets the requirements; if not, adjust it again following the aforementioned procedure.
(5) Direction Adjustment: 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, it can be operated repeatedly. 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 travel.
