Overview
The DZW series electric actuators for valves are our company's improved and refined version of a mature product, optimizing protection performance and key components. It is a completely self-developed new generation product with 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 adjustment.
The DZW series is used for controlling the opening and closing of valves. Suitable for gate valves, stop valves, check 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 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 Valves) and meets the specifications of GB3836.1-2000 (Part 1 of Electrical Equipment for Explosive Gas Environment: General Requirements), GB3836.2-2000 (Part 2 of Electrical Equipment for Explosive Gas Environment: Flameproof "d"), as well as JB/T8529-1997 (Technical Conditions for Flameproof Electric Actuators).

Three: Adjust
Adjusting torque, while traversing, 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) 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; typically, the torque for the open direction is greater than that for the close direction.
(4) Adjustments are made under conditions of no load, no medium pressure, etc. When there is pressure and 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°, thus separating the driven small gear from the counter's unit gear set.
(3) Rotate the "Off" adjustment shaft with a screwdriver in the direction of the arrow until the cam presses down on the spring plate, causing the microswitch to activate. This indicates that the initial "Off" stroke is 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 aforementioned 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, and the opening stroke is complete. After adjusting the stroke control mechanism, the operation can be repeated several times. Generally, the valve is opened to about 90%.
3. Adjustments for the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
