Overview
The Non-Spring Return Electric Linear Valve Actuators have floating or modulating control. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. Floating control actuators are used with controllers that provide a switched or floating single-pole double-throw (SPDT) output. Modulating control actuators are used with controllers that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc.
