CAMOZZI Valves - Manual, Mechanical & Air-Pilot

Air-Pilot Valves - Series NA Valves (NAMUR Interface)

Series NA Valves (NAMUR Interface) Cv= 1.05

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

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.
