Pneumatic coaxial valves "FASTAIR"

The original design of these valves allows the use especially for the control of vacuum, gaseous, liquid, contaminated media compatible with the materials used.

Advantages of use:

  • the valve is pressure relieved - operation is independent of the internal fluid pressure
  • axial medium flow, high flow coefficient with small pressure drop
  • magnetic design - easy sensing of the valve position with a standard switch
  • easy installation in any position, without external moving parts
  • small overall external dimensions, without external drive
  • long-life fluid seal
  • easy maintenance and possible replacement of the valve seal
  • low control air consumption
  • easy connection of the control valve - NAMUR

Principal:

There are two basic types of valves, namely double-acting and single-acting. Single-acting then NC and NO. These valves are available in six different versions from size DN 15 (1/2 ") to size DN 50 (2").

The coaxial valve includes a pneumatic actuator, which can be controlled via a G 1/8 “connection or via a solenoid valve with a NAMUR flange. The valve therefore opens / closes with a pneumatic signal.

Treatment:

HARD ANODIZING 

Electrolytic process that produces an anodic layer on aluminum (ALUMINE), with 50 um thickness. Alumine is one of the hardest known materials, surface hardness 400-600 HV (45-65 HRC). Its mechanical properties and chemical resistance are well appreciated.

ELECTROLESS NICKEL-PLATING 

Electroless chemical process gives a nickel and phosphor (max 12%) layer. 20 um constant thickness also on shapes, blind-holes, threads and recesses. Surface hardness 400-480 HV (45-55 HRC).

HARD ANODIZING + PTFE COATING 

It is a further improvement of hard anodizing, with a 20 um coating made of PTFE. Oxide hardness (for internal parts subject to wear), and excellent chemical/thermal resistance of PTFE (for external surfaces subject to corrosion) are summed.
