Three: Adjust

Adjusting torque, during travel, 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 completely closed.

(3) Adjust the torque for switch direction based on the valve's operational characteristics; typically, the open direction torque is greater than the close direction 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 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) 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 single-digit gear assembly of the counter.

(3) Rotate the "Off" adjustment shaft with a screwdriver in the direction of the arrow until the cam presses down on the spring plate, causing the microswitch to activate. This indicates that the "Off" travel has been initially adjusted.

（4） 

At this point, turn the electric switch a few rotations and then turn it off. Check if the closing stroke meets the requirements; if not, adjust according to the aforementioned procedure.

(5) Direction Adjustment: After the valve is adjusted in 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 opening stroke is complete. After adjusting the stroke control mechanism, repeat the operation a few times. Generally, the valve is opened to about 90%.

3. Adjustment of the adjustable opening indicator:

Adjust the adjustable opening indicator and remote potentiometer after adjusting the torque and stroke.
