RE SERIES – ALPHAIR ALUMINIUM PNEUMATIC ACTUATORS
Alphair aluminium pneumatic actuators “RE Series”, with external adjustment, is composed of 15 models with 90° movement, going from 20 to 10.000 Nm for the double acting version (DA) and from 4 to 4000 Nm for the single acting version (SR).
Open/close regulation level of the valve is fast and easy, thanks to the external adjustment system, acting on the cam movement through grains on the body.
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. Product can be customized through hard anodizing, nickel-plating and painting.
