Belimo F6100HDU Valve Assembly
The Belimo F6100HDU is a high-performance 4-inch 2-way butterfly valve designed for demanding commercial HVAC and industrial hydronic systems. This ductile iron lug-style valve features an undercut 304 stainless steel disc specifically engineered for 50 psi close-off pressure, making it an ideal solution for chiller isolation, cooling tower bypass, and large air handler coil control. With a flow coefficient of 600 Cv and a modified equal percentage characteristic, this assembly provides precise modulation for water or glycol solutions up to 60% concentration.
Built for durability in the field, the F6100HDU valve assembly utilizes a 416 stainless steel stem and a heavy-duty EPDM resilient seat to ensure bubble-tight shut-off (0% leakage). The valve body is finished with a blue epoxy powder coating to resist corrosion, while the RPTFE bearings ensure smooth operation under varied load conditions. This assembly is compatible with ANSI Class 125/150 flanges and maintains a wide fluid temperature range of -22°F to 250°F, allowing for flexible installation in both heating and cooling loops.
Key Benefits:- Application Versatility: Optimized for chiller isolation and bypass applications requiring lower differential pressure across the disc.
- Superior Material Construction: Features a 304 stainless steel disc and 416 stainless steel stem for high-cycle reliability and longevity.
- Zero Leakage Performance: The resilient EPDM seat provides bubble-tight shut-off, preventing energy loss in bypass and switch-over systems.
- Installation Ready: Designed for direct mounting with Belimo actuators; the long stem allows for up to 2 inches of pipe insulation without interference.
- What is the difference between the HD and HDU models? The HDU (undercut) model, such as the F6100HDU, is rated for a 50 psi close-off to reduce torque requirements, whereas HD models are rated for 200 psi.
- Can this valve be used in steam applications? No, this assembly is strictly for chilled or hot water and glycol solutions up to 60%.
- Does this valve support bidirectional flow? Yes, the butterfly valve assembly is designed for 2-way flow control and can be installed in various orientations.
