AP-serie Alphair Aluminium Actuator

Heavy Duty, Maximum Lifetime

The aluminium pneumatic actuators of the AP-serie of Alphair is composed of:

  • 17 different models with 90° movement, going from 7 to 10.000 Nm for the double acting version (DA) and from 4 to 4000 Nm for the single acting version (SR);
  • 11 models with 120° and 180° movement, going from 7 to 700 Nm for the double acting version (DA) and from 4 to 120 Nm for the single acting version (SR).

The internal rotation adjustment system, acting on pistons and covers, avoids side-loads on pistons, shaft and body at every feeding pressure.
It assures to the product: compactness, sturdiness, reliability and long-lasting. These series can be coupled with every ISO 5211 compliant valve. Moreover it can also be coupled with valves not in compliance with the a.m. certification. Easy assembly/change on every mean of valve.
Product can be customized through hard anodizing, nickel-plating and painting.
