I: Overview
The DZW series electric actuators for valves are our company's improved and refined version of mature products, featuring optimized protection performance and critical components, and are a completely independently developed new generation of products. They offer compact structure, small size, attractive appearance, and stable and reliable performance. With a good protection grade, they can meet the needs of various designs: explosion-proof, all-position switching, and all-position regulating.
The DZW series is used to control 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 dampers, etc. It can accurately actuate according to control commands, and is an indispensable driving device for remote, centralized, 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 Atmospheres: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Atmospheres: Explosion-Proof "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 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 above are made under conditions of no load and no medium pressure. When there is pressure and temperature, attention should be paid 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. Traveler control mechanism adjustment:
(1) Manually close the valve tightly.
(2) Disengage the stroke control mechanism by using a screwdriver to push the plunger in the stroke control mechanism and turn it 90°, thereby separating the driving sprocket from the counter's unit gear set.
(3) Rotate the "Off" position screwdriver towards the adjustment shaft, turning according to the arrow direction until the cam presses the spring plate, causing the microswitch to activate. This indicates that the "Off" travel has been 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 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, the operation can be repeated 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 gear and travel.
