Belimo F6125HDU Valve Assembly
The Belimo F6125HDU is a professional-grade 5-inch 2-way butterfly valve designed for high-capacity flow control in commercial hydronic systems. This ductile iron butterfly valve features a 304 stainless steel disc and an EPDM liner, ensuring bubble-tight shut-off and zero leakage up to a 50 PSI close-off pressure. With a high flow coefficient (Cv 1022), it is optimized for chilled water, hot water, and up to 60% glycol solutions. The F6125HDU valve assembly is engineered to meet the rigorous demands of HVAC contractors, providing low-torque operation and reliable isolation in standard ANSI Class 125/150 piping circuits. Whether used for central plant applications or large air handling units, this heavy-duty assembly ensures long-term performance under high-flow conditions.
Key Benefits for Contractors:
- Bubble-Tight Sealing: The EPDM liner and stainless steel disc provide 0% leakage up to 50 PSI, preventing energy loss and system bypass.
- High Flow Efficiency: A Cv of 1022 minimizes pressure drop across the 5-inch port, reducing pump head requirements and operational costs.
- Durable Construction: The ductile iron body (ASTM A536) offers superior strength compared to standard gray iron, making it suitable for high-stress mechanical rooms.
- Media Compatibility: Rated for a wide temperature range and chemical resistance against standard water treatment and glycol concentrations.
- Standardized Integration: Compatible with various Belimo actuators for precise modulating or on/off control in building automation systems.
Common Questions:
What is the maximum close-off pressure for this assembly?
The F6125HDU is rated for a maximum close-off pressure (COP) of 50 PSI. For applications requiring higher pressure ratings, please verify your system head requirements before installation.
Can this valve be used for steam applications?
No, this assembly is specifically designed for water and glycol-based hydronic systems. The EPDM liner is not rated for high-pressure steam service.
Is this model a wafer or lug-style body?
The F6125HDU features a standard HDU series configuration designed for easy installation between ANSI flanges, common in 5-inch industrial pipe schedules.
