PNEUMATIC ACTUATOR

Categories : ACTUATOR

     Valbia pneumatic actuators, available in spring return or double acting version, with 0°-90° standard rotation or 0°-180°. This type of actuator is mainly used in industrial processes, to automate interception and adjustment devices. 
      Using carefully selected materials, Valbia offers a product with a unique patented design, which is able to guarantee high quality standard, performance and strong reliability throughout its useful life.

     The possibility to use various types of construction materials and combinations, makes Valbia actuators versatile and suitable to different applications and operating environments; the certifications, achieved by the products, allow the usage in all the major industrial sectors (from food & beverage to the O&G market), both in European and International contest. Valbia is able to propose the most suitable solution according to the different requirements of use and to provide also a wide range of accessories such as solenoid valves, limit switches, positioners, emergency gear operators and levers for manual intervention.
Three series of pneumatic actuators are realized:
     • the Series 82, aluminum with 0°-90° rotation;
     • the Series 83, aluminum with 0°-180° rotation;
     • the Series 84, stainless steel with 0°-90° rotation.

In addition to the standard versions, Valbia offers a wide range of special versions designed to provide specific solutions for any need.
