I: Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed through improvements and optimizations on our existing mature products. They feature a compact structure, small size, attractive appearance, and stable and reliable performance. The good protection grade meets the needs of various designs: explosion-proof, all-position switch, and all-position regulating.
The DZW series is designed for controlling the opening and closing of valves. Suitable for gate valves, stop valves, check valves, diaphragm valves, its derivative products can be used for ball valves, butterfly valves, and dampers, etc. It can accurately respond to control commands, making it 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 Type "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjusting the torque, during travel, it is essential to check if 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) Start from 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 opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no load and medium pressure. When there is pressure or 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. 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 driving small gear from the individual gear set of the counter.
(3) Rotate the "Off" adjustment shaft with a screwdriver in the direction of the arrow until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the initial "Off" travel has been properly adjusted.
（4）
At this point, you can turn the switch a few times electrically, then turn it off. Check if the closing travel 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 micro-switch to activate. Reengage the stroke mechanism with the driving gear, and the opening stroke is complete. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, the opening of the valve is controlled around 90%.
Adjustment of the adjustable opening indicator:
(1) Adjust the adjustable opening indicator and remote potentiometer after tuning the gear ratio and travel.
