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.

The 83 series, with an extruded and hard anodized aluminum body, is manufactured in 9 models to guarantee a wide range of choice according to the requested torque; it allows a 0°-180° rotation with the possibility to adjust the run of the pistons by using the cam adjustment and the bolts mounted on the end caps. 

The Valbia 83 series is only available in the double acting (DA) versions.

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,
