Belimo F6100HDUSY2-110 SY2-110 Rotary Actuator

Belimo F6100HDUSY2-110 is a factory-assembled valve-actuator kit that pairs the Belimo F6100HD butterfly valve with a SY2-110 rotary actuator for HVAC damper control in air‑distribution systems. The F6100HD butterfly valve supports valve sizes up to 4 inches and uses a disc made from 304 stainless steel, offering durability and corrosion resistance in ductwork environments. The SY2-110 actuator provides 120 VAC operation for two-position control and is designed to position the valve disc reliably when driven by standard control signals. Together, this kit delivers a compact, ready-to-install solution that simplifies integration with building automation systems while preserving Belimo's mounting compatibility and electrical interfaces. It is commonly used to regulate air flow in commercial HVAC applications such as air handlers, VAV boxes, and rooftop units, where a dependable, single-piece valve-and-actuator assembly can reduce install time and ensure consistent damper performance.
