Actuator nomenclature follows the general pattern below:
First digit is torque with letters: T, L, N, A, G, E
Second digit is fail-safe function and "F" means spring return, "K" means electronic fail-safe, and "M" means non-spring return.
Following digit "B" means a basic or standard configuration while "X" means flexible or customizable. Actuators used on rotary valves are indicated by the letter "R" and include factory installed valve linkage.
Middle numbers indicate power supply voltage such as 24, 120, 230, while "UP" indicates a universal power supply.
Last digits indicate the control signal input where "-SR" means 2-10VDC proportional control (not spring return), "-3" indicates floating and "-MFT" designates Multi-Function Technology programmable actuators.
Models that contain a "-S" have one or more built-in auxiliary switches and "-T" models have terminal blocks not cables. For more specific information see the attached nomenclature chart.
