Product Manual: CVS Rack & Pinion Actuator

Operation Logic

As the input signal is increased, the flapper (2) get pushed by the force of the torque-motor (1). As the

gap between the flapper (2) and the nozzle (3) increases, air pressure bleeds from the pilot valve (4)

and the spool (5). As a result, the spool (5) rises and simultaneously opens the seat (7). This allows air

pressure to discharge through port OUT1 to the actuator (10). As the actuators inner pressure increases,

the actuator stem (12) will move, pushing on the feedback lever (13). This movement is transferred to

the cam (14) and pulls on the feedback spring (16). At the point of balanced force exerted by the input

signal and the feedback spring, the gap between the flapper (2) and the nozzle (3) will decrease,

stopping the movement to the actuator.
