Alphair AP series Aluminium Actuator
Piston Based Actuator
Description
Heavy Duty, Maximum Lifetime
The "AP" Series" from Alphair are aluminium rack & pinion pneumatic actuators.
The series consists of:
- 17 different models with 90° rotation, 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 guarantees compactness, sturdiness, reliability and a long product life.
The above series can be coupled to any ISO 5211 compliant valve. By means of suitable coupling accessories it can also be combined with valves that do not meet this standard. Product can be protected through hard anodizing, nickel-plating or PTFE coating.
