Dimensions in millimeters (mm)
Air-Pilot operated 1/4” NPTF
3-way/2-position; 5-way/2-position; and 5-way/3-position valves
with Interface according NAMUR Standard
Series NA Valves (NAMUR Interface)
Cv= 1.05
The valves Series NA are available in versions:
5-way/2-position and 3-way/2-position, Normally
Closed or Normally Open. These are indirectly actuated
valves and are available in single and double air pilot
versions. The valve has a NAMUR interface pattern and
can therefore be directly mounted on other suitable
components that also have this hole pattern, such as
certain rotary actuators, ball valves or process valves.
The single air pilot version is equipped with a
mechanical return spring.
