Installation

while making sure that the value on the 
scale matches the valve's direction of ro-
tation.

Securing the aligned cam disk

To prevent the cam disk from turning, drill a 
hole into the adapter (4) or coupling (11) to 

allow a 2 mm dowel pin to be inserted.

Select one of the four holes located around 
the center hole of the cam disk to secure the 
cam disk in position.

Double-acting, springless rotary actuator with reversing amplifier
