Description
Overview
The Belimo F6100HD+PRBUP-3-T is a factory-assembled 4-inch, 2-way butterfly valve and actuator combination engineered for demanding commercial and industrial HVAC hydronic systems. Pairing the robust F6100HD high-duty butterfly valve body with the PRBUP-3-T non-spring-return (NSR) actuator, this assembly delivers reliable on/off or modulating flow control in a single, ready-to-install package. The NEMA 4X-rated enclosure ensures protection against corrosion, dust, and water ingress, making it well-suited for indoor and outdoor mechanical room installations.
Key Features
- 4-inch (DN 100) 2-way butterfly valve for hydronic heating and cooling applications
- 120V AC power supply for broad compatibility with standard commercial control systems
- Non-spring-return (NSR) actuator — holds last position on power loss
- NEMA 4X enclosure rating — resistant to corrosion, dust, and water ingress
- Integrated auxiliary switch (AUX) for end-position feedback and interlock wiring
- Factory-assembled valve and actuator combination for simplified installation
- High-duty (HD) valve body construction for extended service life in demanding applications
- Belimo’s proven direct-coupled actuator design — no couplings or linkages required
Application
The F6100HD+PRBUP-3-T is ideal for use in commercial HVAC air handling units, chiller and boiler piping systems, fan coil units, and central plant applications where reliable 2-way flow shutoff or modulating control is required. The auxiliary switch enables integration with building automation systems (BAS) for end-position confirmation and sequencing.
