Rotanting pneumatic actuators

ROTATING PNEUMATIC ACTUATORS

Our actuators
are compact,
sturdy and reliable

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.

HARD ANODIZING

Anodizing is an electrolytic process that produces an anodic coating on aluminium, called alumina, with high thickness. This supplies the product with best fiction and corrosion resistance, best surface hardness, good thermal and electrical insulation.

CHEMICAL NICKEL-PLATING

It is a coating process, without the use of electricity, that lays highly uniform nickel layers also on sharp angels, blind-holes, threads and groove recesses.
It improves fiction and corrosion resistance, surface hardness, resistance to alkali and detergents and it look like stainless steel

POLYESTER PAINTING

Polyester painting is obtained through powder coating on polarized parts, by means of light differences in electrical potentials. After application, the parts are baked in order to polymerize and let the painting be spread, in order to avoid micro-porosity. A satisfactory adhesion to the metal can be assured by sandblasting or brushing, and by special degreasing and grabbing baths to be applied on the rough pieces before treatment.
It improves corrosion resistance, protection against crashes and chemical agents. The product can be cus-tomized in several different shiny colours.

HARD ANODIZING + PTFE COATING

As further improvement of the hard anodizing on aluminium alloys, a protective coating made of polytetrafluoroethylene (PTFE) can be used. On those double treated surfaces, the hardness and low roughness of the oxide (for inside slipping parts) is added to the chemical resistance and to the excellent qualities as a thermal barrier of the PTFE (for outside parts, subject to corrosion).
This process assures corrosion resistance, protection against high temperatures and crashes, extreme resistance to chemical agents, and above all in marine environment.
