I. Overview
The DZW series electric actuators for valves are our company's improved and optimized version of the mature products, featuring enhanced protective performance and critical componentry, and are a completely self-developed new generation product. They boast compact structure, small size, attractive appearance, and stable and reliable performance. The high protection grade meets the needs of various designs: explosion-proof, all-in-one switching, and all-in-one regulating.
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 air gates, etc. It can accurately actuate according 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 performance of explosion-proof type conforms to GB3836.1-2000 (Part 1: General Requirements for Electrical Equipment Used in Explosive Gas Atmospheres), GB3836.2-2000 (Part 2: Explosion-Proof Type "d" for Electrical Equipment Used in Explosive Gas Atmospheres), 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 disengaged (loosen the set screw on the gear of the potentiometer shaft) to prevent damage.
Torque control mechanism adjustment:
Firstly, adjust the closing torque.
(2) Start from a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque of the switch direction based on the valve's operating characteristics; generally, the opening torque is greater than the closing torque.
(4) The adjustments mentioned above are made under conditions of no load and without medium pressure. When there is pressure or temperature, attention should be paid to whether it can be sealed tightly. If it cannot be sealed properly, the torque value should be appropriately increased to ensure it can be tightly sealed and easily opened.
2. Traveler 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" position screwdriver towards the adjustment shaft, turning until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the "OFF" travel 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) Adjustment of Opening Direction: After the closing direction is adjusted, manually open the valve to the required position. Then, disengage the stroke control mechanism, rotate the "open" adjustment shaft in the direction of the arrow until the cam presses the spring plate, causing the micro-switch to activate. Reengage the stroke mechanism with the driving gear to complete the opening stroke adjustment. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, control the opening of the valve at about 90%.
3. Adjustable opening degree indicator adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and travel.
