AP-A SERIES – ALPHAIR STAINLESS STEEL ACTUATORS

Alphair AISI 316 stainless steel pneumatic actuators “AP-A Series”, with internal adjustment, is composed of 10 models with 90° movement, going from 13 to 520 Nm for the double acting version (DA) and from 4 to 200 Nm for the single acting version (SR); 8 models with 120° and 180° movement, going from 13 to 360 Nm for the double acting version (DA).
The internal adjustment system, acting on pistons and covers, avoids side-loads on pistons, shaft and body. It assures compactness, sturdiness, reliability and long-lasting to the product.
The above mentioned 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
