Actuator

The Package actuator contains the Valbia 82 series DA (Double Acting)

Valbia manufactures rack and pinion pneumatic actuators, available in spring return or double acting version, with 0°-90° standard rotation or 0°-180°, and are standardly furnished with VITON seals. Valbia offers a product with a unique patented design, which is able to guarantee high quality standard, performance and reliability.Valbia actuators are versatile and suitable to different applications and operating conditions.
Valbia pneumatic actuators are available in three versions:

• The 82 series aluminum with 0°-90° rotation
• The 83 series aluminum with 0°-180° rotation
• The 84 series stainless steel with 0°-90° rotation

The 82 series, with an extruded and hard anodized 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 is available in the spring return (SR) or double acting (DA) versions.

Actuator Features

• Concentric spring sets
• Die cast aluminum end caps
• Solid steel barstock pinion (not casting)
• 0°-90° rotation adjustment cam
• 0°-90° rotation adjustment bolts
• POM piston guides
• Mininum air pressure rating: 80 psi Max: 116 psi
• Working temperature: -4°F - 302°F
• No lubrication maintenance required for the entire actuator lifetime

Valve Size with Actuator DA (Double Acting)

Actuator Sizing For Pneumatic Spring Return

The output torque of a spring return actuator is not consistent but decreasing. This is due to the action of the springs. When compressed by the air pushing out the pistons, they accumulate energy which will be available in a decreasing way during the clockwise rotation inversion. Please consult the information below for torque calculation.
