Actuator

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

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,

DA - Double Acting Torque chart

Valve Size with Pneumatic Spring Return Model

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.

Positioner ENP-B

The package also includes the Bonomi ENP-B 4-20mA Electro-Pneumatic Positioner

• Compatible with most controllers
• Easy Maintenance because of modularized inner structure
• Split Range 4-12 mA or 13-20 mA can be set with simple adjustment
• Low air consumption
• Simple direct/reverse action change
• Simple zero and span adjustment
• Orifices can be installed in the field to minimize hunting occurrence and optimize operating conditions
• It has IP66, type 4X (FM) ingress protection grade
• Epoxy polyester powder coating resists the corrosion process
