I: Overview
The DZW series electric actuators for valves are a new generation of products that our company has developed and improved upon our mature products, optimizing protection performance and key components. They are entirely self-developed, featuring a compact structure, small size, attractive appearance, and stable and reliable performance. The good protection grade meets the needs of various designs: explosion-proof, overall on/off, 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's performance complies with the requirements of JB/T8528-1997 (Technical Conditions for Electric Actuators for Valves of General Type). The explosion-proof type meets the standards of 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, ensure 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 the switch direction based on the valve's operating characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments are made under conditions of no load, no medium pressure, etc. 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. Cruise Control 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 pinion from the counter's unit gear set.
(3) Rotate the "Off" position using a screwdriver to adjust the shaft, turning until the cam engages the spring plate, causing the micro-switch to activate. This indicates the initial adjustment of the "Off" travel is complete.
（4）
At this point, you can electrically turn it a few rotations, then close it. Check if the closing travel meets the requirements; if not, adjust it again following the above procedure.
(5) Direction Adjustment: After the valve is adjusted in the closed direction, 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 actuate. Reengage the stroke mechanism with the driving gear to complete the opening stroke adjustment. After adjusting the stroke control mechanism, the operation can be repeated several times. Generally, the valve opening is controlled around 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the gear and travel.
