Air operated valves are often used in areas where electrical signals would pose a hazard, or when air pressure control exists or is preferred. NITRA 5-port (4-way) spool valves are available with single-pilot spring return or double-pilot 2-position operation. Double-pilot models are also available in a 3-position center-closed configuration.
Pneumatic Directional Control Valves - AVS-5 Series Air Pilot
NITRA® pneumatic AVS-5 series directional pilot
control valves are body ported 5-port (4-way) spool valves.
Available port sizes are 1/8", 1/4", 3/8" or 1/2" NPT
with flow coefficients (Cv) from 0.67 to 2.79.
These air operated valves are available with single pilot
spring return or double pilot 2-position operation.
In addition, double pilot models are available with
3-position center closed operation.
The AVS series can be used in individual pilot operated
valve applications, or multiple valves can be field assembled on
AM-5 series manifolds for simplifying piping connections (AVS-52
& AVS-53 series only).
AM- 5 series manifolds are available in 2, 4, 6 or 8
