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 existing mature products. They feature a compact structure, small size, attractive appearance, and stable and reliable performance. The good protection level meets various design requirements: explosion-proof, overall on/off, and overall regulating types.
The DZW series is used for controlling the opening and closing of valves. It is 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, making it 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 Type 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) Begin with 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 operational 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 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. 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 turn it 90°, thereby 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 engages the spring plate, causing the microswitch to activate. This indicates that the "Off" stroke is initially adjusted.
（4）
At this point, you can turn it a few rotations electrically, then close it. Check if the closing stroke meets the requirements. If not, adjust it again following the above procedure.
(5) Direction Adjustment: After the closed 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 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 opening of the valve is controlled around 90%.
3. Adjustment of the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
