I: Overview
DZW Series electric actuators for valves are our company's improved and optimized version of a mature product, enhancing protection capabilities and critical components, and a completely independently developed new generation product featuring compact structure, small size, aesthetic appearance, and stable and reliable performance. The good protection grade meets various design requirements: explosion-proof, full-range switch type, and full-range regulating type.
The DZW series is used for controlling 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 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 specifications 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 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 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 torque.
(2) Start from 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 operating characteristics; generally, the open direction torque is greater than the close direction torque.
(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 tightly sealed, 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 pinion from the counter's unit gear set.
(3) Rotate the "OFF" position adjustment shaft with a screwdriver in the direction of the arrow until the cam presses against the spring plate, causing the microswitch to activate. This indicates that the initial "OFF" position travel is properly adjusted.
（4）
At this point, you can electrically turn it a few rotations, then close it. 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 desired 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 microswitch to actuate. Reengage the stroke mechanism with the driving gear, and the opening stroke adjustment 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. Adjustable Opening Indicator Adjustment:
(1) Adjust the adjustable opening indicator and remote potentiometer after tuning the torque and stroke.
