Pneumatic Actuator Double Acting Valbia - DA52

The series 82, with an extruded aluminum body, is manufactured in 15 models to guarantee a wide range of choice according to the requested torque; it allows a 0°-90° rotation and it is available in the spring return (SR) or double acting (DA) versions.

The pneumatic actuator has a patented solution for the cam and the double adjustment stop bolts chamber. Such area is separated from the pistons chamber. This solution reduces the eventual leaking points and it enables better performances and long-term reliability of our actuators.

BODY MANUFACTURED FROM EXTRUDED ALUMINIUM EN AW-6063:
