3. Product type selection


Remark:

The product is only used for single-acting line stroke actuator. It is suggested to match the actuator of 40-100 mm internal gas chamber diameter.


4. Interface angle adjustment


The angle can be adjusted between the positioner and the valve. If need to adjust the interface angle, rotate the main body casing clockwise or counter-clockwise in 180°range.
