Actuator

The Package actuator contains the Valbia 82 series SR (Spring Return)

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 SR (Spring Return)

Actuator Sizing For Double Acting

The torque of a double acting actuator remains consistent throughout the complete action. The actuator can be sized using the following guidelines as to the manufacturer's suggested settings:

• Define the maximum torque of the valve
• Increase the torque value by 25% to 50% to add a safety factory (subject to the valve and working conditions)
• Use the torque chart below to considering the available air pressure find a torque value exact to or exceeding the one obtained.
• Move horizontally in the chart below to find sufficient actuator output torque. Please click on the table below to expand,

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.
