Three - Position Pneumatic Actuator

3-Position pneumatic actuators 90°provide an operation of 0°-arbitrary angle-90°for 90°actuator rotation.The intermediate position is achieved by an external mechanical stop with 2 auxiliary pistons(for spring return actuators it may be only one auxiliary piston). The required adjustable intermediate position may be easily obtained by adjusting the external nuts located outside the two end-caps.Both types,double acting and spring return,are available.Field of application:for dosing,for car loading valves and for any kind of services where on 90°rotation an intermediate stop position is desired.
