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, aesthetically pleasing appearance, and stable and reliable performance. The good protection grade meets various design requirements: explosion-proof, full on-off, and full adjustment types.
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 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 for Valves of General Type). The explosion-proof model's performance complies with 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 "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) Begin with 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 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. Travel control mechanism adjustment:
(1) Manually close the valve tightly.
(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 sprocket from the counter's unit gear set.
(3) Rotate the "OFF" position with a screwdriver until the cam engages the spring plate, following the arrow direction until the microswitch actuates. 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 stroke meets the requirements. If not, adjust it again following the above procedure.
(5) Direction Adjustment: After the direction is adjusted in the closed position, 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 engages the spring plate, causing the micro-switch to activate. Reengage the stroke mechanism with the driving gear, and the adjustment of the opening stroke is complete. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, control the valve opening to about 90%.
3. Adjustable opening indicator adjustment:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and travel.
