Linear actuator JHA series

rotarypneumaticrack-and-pinion

3 position pneumatic actuator is an actuator of special specification, which can provide 0°-180° three-position operation modes.The intermidiate position is operated through mechanical braking of two auxiliary pistons’ movement.The middle position is adjustable, such as the actuator of 90° angular stroke can provide 20°, 30°, 50°, 70° and other intermediate positions. 2.
