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 used for controlling the opening and closing of valves. Suitable for gate valves, stop valves, check valves, diaphragm valves, its derivative products can be applied to ball valves, butterfly valves, and air gates, etc. It can accurately respond 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 types 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 disconnected (loosen the set screw on the gear of the potentiometer shaft to disconnect) 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 direction based on the valve's operational characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no load and no medium pressure. When there is pressure and temperature, pay attention to whether it can be tightly sealed. If it cannot be sealed tightly, increase the torque value appropriately to ensure it can be tightly sealed and easily opened.
2. Traveler control mechanism adjustment:
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 pinion from the counter's unit gear set.
(3) Rotate the "Off" position with a screwdriver towards the adjustment shaft, turning until the cam engages the spring plate, causing the microswitch to activate. This indicates that the "Off" travel has been initially adjusted.
（4）
At this point, turn a few circles electrically, then close it. Check if the closing travel 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 until the cam presses the spring plate, causing the micro-switch to activate. Reengage the stroke mechanism with the driving gear for the opening stroke to be complete. After adjusting the stroke control mechanism, the operation can be repeated several times. Generally, the opening of the valve is controlled at about 90%.
Adjustment of the adjustable opening indicator:
(1) Adjust the adjustable opening indicator and remote potentiometer after tuning the gear ratio and travel.
