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 84 series also features:

• High Temperature as Standard - to withstand temperatures up to 302° Fahrenheit (150° C)
• Low Temperature Option: For Applications that require the use down to -40° Fahrenheit (-40° C)
• P303 Stainless Steel pinion

The 84 series presents the same compact design and the same technical features of the 82 series, but it has stainless steel (A351 CF8M) body, caps and pinion, and is available in 5 models.

Actuator Sizing

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 guidelines:

• 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,
