Coaxial valves for fast, reliable switching

A coaxial valve combines the shut-off function and the pneumatic actuator in one compact body. An axially moving piston opens and closes the seat, without external moving parts. Because the seat is fully tight, the required control pressure is independent of the medium pressure — giving fast, reliable switching with a full bore and minimal pressure loss. Available as double acting or spring return (NO/NC) with NBR, FKM or EPDM seals.
