Controller: Positioner, Plastic
The KMC CMC-1001 non-metallic positive positioner is designed to work with KMC pneumatic damper actuators. CMC-1001s can be factory-mounted or field-installed on 3", 4", or 6" stroke actuators.
The CMC-1001 is designed to be used with actuators containing an 8 to 13 psi spring so that equal force can be obtained on both power and return strokes. The CMC-1001 replaces positioners on any MCP actuator with the digit 1 in the fifth position (MCP-xxxx-1xxx).
The start-point is adjustable from 3 to 10 psi. The overall span is a direct function of the selected feedback spring, which is ordered separately (see Accessories section).
NOTE: For all 3" and 4" actuators, insert the (included) VTD-2500 restrictor in the line between Port #1 and the actuator. The restrictor is not needed on 6" actuators.
