Namur Valves
Features
These valves are used for directly mounting onto the actuator via the NAMUR interface. Direct Acting, Internal or External pilot valves are available, with 3/2, 5/2 & 3/2 5/2 convertible constructions. Flow rates available from Kv1.8 to 12 l/min. Certain models have common ports for both pneumatic & spring vent that allows the spring chamber to be always purged with instrument air, thus improving the life of the springs in corrosive environments.

Body Ported Valves
Features
These are used for remotely mounted pilot valves for spring return or double acting actuators. Direct Acting, Internal or External pilot valves are available, with 3/2, 5/2 & 5/3 constructions. Orifice sizes from 0.8mm to 50mm, with flow rates available from Kv0.8 to 650 l/min. Certain models have common ports for both pneumatic & spring vent that allows the spring chamber to be always purged with instrument air, thus improving the life of the springs in corrosive environments.
These valves are also used for Instrument Changeover and Process Control in hazardous areas.
