The EN132C2(-S), EN177C2(-S) and EN310C2(-S) direct coupled 24 VAC non-spring return (NSR) rotary electronic actuators are designed for tri-state (floating) or two-position control of building HVAC dampers and valves.
The EN132B2, EN132B2-ZS-S, EN177B2(-S), EN177B2-ZS(-S), EN177D2(S), EN310B2(-S), EN310B2-ZS(-S) and EN310D2(-S) direct coupled 24 VAC non-spring return (NSR) rotary electronic actuators are designed for modulating control of building HVAC dampers or valves.
These actuators are used in constant or variable air volume installations for the control of return air, mixed air, exhaust, and face and bypass dampers and valves requiring up to 132 in-lb (15 N-m), 177 in-lb (20 N-m), or 310 in-lb (35 N-m) torque.
