The Connexion 281 Series 2/2 coaxial pneumatic valve has been developed for the control of vacuums and gaseous, liquid, gelatinous, abrasive, contaminated, and aggressive media up to 160 Bar.
The co-ax valve design allows - as compared to conventional solenoid valves  - high pressure aggressive or contaminated media bi-directional control with high flow rates.

Connexion coaxial valves are available in 2/2 way or 3/2 way versions with threaded, flanged or manifold connections.
Actuation either by direct-acting solenoid or external pilot control.
Additional options include ATEX coils and position indication, high temperature applications and other custom made modifications to suit customer applications.
 
Sizes range from 1/4 BSP DN10 to 11/2 DN25
New DN32 and DN40 2" BSP and above available soon.
