Description
The KMC MEP-455 Series direct-coupled, spring-return actuators are designed to control dampers and valves requiring fail-safe operation.
The MEP-455 series actuators mount to 3/8″ to 1″ diameter shafts or 1/4″ to 3/4″ square shafts. The actuators produce 160 in-lbs. of torque, running and spring return minimum, over a maximum 95? rotation. (This series was previously rated at 142 in-lbs. but was re-rated at 160 when a more powerful motor was incorporated.)
Two-position and 0 to 10 VDC models are available with pre-cabled wiring and integrated conduit adapter.
