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 mature products. They feature a compact structure, small size, attractive appearance, and stable and reliable performance. The good protection grade meets various design requirements: 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 derivatives can be used for ball valves, butterfly valves, and air gates, etc. It can accurately operate according 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 of General Valves) and meets the specifications 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, and 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) Begin with a low torque value and gradually increase it until the valve is fully closed.
(3) Adjust the torque of the switch direction according to the valve's operating characteristics; generally, the opening torque is greater than the closing torque.
(4) Adjustments are made under no-load, no-medium pressure conditions, etc. When pressure and temperature are present, attention should be given to whether it can be tightly sealed. If it cannot be tightly sealed, 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 plunger in the stroke control mechanism and rotate it 90°, thereby separating the driving pinion from the counter's unit gear set.
(3) Rotate the screwdriver clockwise towards the adjustment shaft, and turn until the cam engages the spring plate, causing the micro-switch to actuate. This indicates that the off position travel is initially adjusted.
（4）
At this point, turn the electric switch a few rotations and then turn it off. Check if the closing travel meets the requirements. If not, adjust according to 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 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, the valve is opened to about 90%.
3. Adjustable Opening Indicator Adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and travel.
