Schneider Electric AK-42309-500 Pneumatic Positive Positioner Relay and Linkage

The Schneider Electric AK-42309-500 Pneumatic Positive Positioner Relay and Linkage delivers precise control for pneumatic actuators. This unit features a direct-action, pilot-operated design for reliable, repeatable positioning in demanding industrial environments.

Designed for compatibility with Pneumatic Actuator systems, it is used on VB-7000, MK-2690-0-0-1, MK-2690-0-0-2, and M556 assemblies. It combines a compact footprint—4-1/2 inch W x 3 inch D x 2-1/2 inch H—with a polysulfone housing and a neoprene diaphragm for durable performance.

Operational specs and environment ensure dependable operation: air supply 15-20 PSIG nominal (up to 30 PSIG max); operating temperature 32-140 deg F (shipping range -40 to 160 deg F); enclosure rating NEMA 1; flow 860 SCIM; humidity 5-95% RH non-condensing.
