Technical information

ACTUATORS: force to be developed, available pressure, maximum stroke in relation to rod cross-section, provision for magnetic limit switches, dampable energy, dimensional standards and materials.

VALVES: pressure, flow rate to be delivered, response times, control type, electrical power, single or manifold mounting, dimensional standards of mounting surfaces.

AIR TREATMENT: required flow rate, filtration degree, lubrication requirements, accessories for pressure control and display.

FITTINGS: operating pressure, thread sealing type, tube to be used, shut-off devices.

The charts and tables presented in the following pages are useful in selecting the type and size of pneumatic components.

 

MECHANICAL INFORMATION

Operating conditions of actuators during their service life

MOUNTING: Unless specific written agreements exist, the actuator and its load must be mounted according to the instructions in the general catalog using appropriate mounting tools and proper screw tightening torques in relation to the materials constituting the threaded coupling.

WORKING CONDITIONS: Unless specific written agreements exist, the expected operating conditions (temperature, pressure, speed, fluid, dampable energy and allowable loads) are specified in the general catalog.

The expected operating conditions for magnetic sensors including accessories and actuators with potentiometer are specified in the general catalog and in the instruction sheets attached to the product or downloadable from the website.

The operating conditions for products bearing 2014/34/EU marking are specified in the "OPERATING INSTRUCTIONS" document attached to the product.

ENVIRONMENTAL CONDITIONS: Unless specific written agreements exist, for all actuators excluding "STAINLESS STEEL ACTUATORS", the environmental conditions of use must prevent the occurrence of penetrating corrosive phenomena (pitting or pitting corrosion, hydrogen embrittlement and especially stress corrosion), therefore chlorinated and sulfurated atmospheres must be avoided (e.g., marine environments, volcanic areas and zones with high concentrations of acidic or basic smog).

Regardless of environmental conditions, during periods of prolonged inactivity, if the rod remains in a position that is not completely retracted, apply a protective lubricant compatible with the rod seal compound.

In the case of "STAINLESS STEEL ACTUATORS", contact AIRON.

MAINTENANCE: must be performed when one of the following conditions is reached:
Detection of significant air leaks (or any evident irregularity in operation);
Distance "L" equal to 500 km (L[Km]=2×stroke [mm]×number of cycles/1,000,000);
Once a year.

Maintenance must be performed by qualified technical personnel who must carry out the following phases:
a) visual inspection of the integrity of the actuator components (presence of dents on rod and cylinder) and absence of corrosive and
abrasive phenomena on the rod and inside the cylinder and verification (if present) of pneumatic cushioning functionality and magnet integrity.
b) Replacement of all seals with original products.
c) Cleaning and greasing of all components with AIRON grease.
