Pneumatic actuators

Alpha pompe S.p.A. manufactures pneumatic actuators for many different purposes. ALPHAIR pneumatic actuators are compact, sturdy and reliable. They are perfectly interchangeable and suitable for every kind of valve, and, when used in their proper way, they can also last longer. ALPHAIR pneumatic actuators are the out come of the best know-how in design and manufacturing.

Alpha pompe produces pneumatic actuators with extruded aluminium body, die-casted aluminium alloy pistons and covers and carbon stainless steel shafts; moreover it manufactures pneumatic actuators with forged stainless steel body, micro-casted stainless steel covers, die-casted aluminium alloy pistons and stainless steel shafts.

Alphair pneumatic actuators, series I, Y and X have an internal adjustment system that avoids side-loads on pistons, shaft and body at every feeding pressure in the end-run position. The RE series is provided with an external adjustment system, that offers high precision on rotation adjusting, even in complicated applications. Suitable for every requirement, they are carefully designed to give you best performances and to last long.
