Restrictors
● Reduce the air output to achieve travel times of T > 1.5 s for small actuators. Use
restrictors Y1
● When turned clockwise, they reduce the air output and finally shut it off.
● In order to set the restrictors, we recommend closing them and then opening slowly.
● In case of double-acting valves, ensure that both restrictors have approximately the same
setting.
