Overview
The DZW series electric actuators for valves are our company's improved and optimized version of a mature product, featuring enhanced protection performance and critical componentry, and are a completely independently developed new generation of products. They boast advantages such as compact structure, small size, attractive appearance, and stable and reliable performance. The high protection grade meets the needs of various designs: explosion-proof, overall on-off type, and overall regulating type.
The DZW series is used for controlling the opening and closing of valves. It is suitable for gate valves, stop valves, check valves, diaphragm valves, and its derivatives 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 Valves) and the performance of explosion-proof types conforms to GB3836.1-2000 (Electrical Equipment for Explosive Gas Atmospheres: General Requirements), GB3836.2-2000 (Electrical Equipment for Explosive Gas Atmospheres, Part 2: Explosion-Proof "d"), and JB/T8529-1997 (Technical Conditions for Explosion-Proof Electric Actuators).

Three: Adjust
Adjust the torque during travel; ensure 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 for switching direction based on the valve's operating characteristics; typically, the opening torque is greater than the closing torque.
(4) Adjustments above are made under conditions of no load, no medium pressure, etc. When there is pressure and temperature, attention should be paid to whether it can be sealed properly. If it cannot be sealed properly, 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°, thereby separating the driving small gear from the counter's unit gear set.
(3) Rotate the "OFF" position using a screwdriver towards the adjustment shaft, turning according to the arrow direction until the cam engages the spring plate, causing the microswitch to activate. This indicates the initial adjustment of the "OFF" stroke 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 aforementioned procedure.
(5) Adjustment of Open Direction: After adjusting 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 open direction 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%.
Adjustment of the adjustable opening indicator:
Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
