Danfoss 009G024 Shut Off Valve

The Danfoss 009G0242 (BML 12s) is a professional-grade shut off valve designed for integration into liquid, suction, and hot gas lines within refrigeration and air conditioning systems. This high-reliability 1/2 inch ODF solder valve facilitates rapid system isolation during servicing or component replacement. Engineered with a robust brass body, the Danfoss BML valve features a handwheel-operated diaphragm that ensures a hermetic seal, preventing refrigerant loss. It is compatible with a wide range of fluorinated refrigerants, including R410A, R404A, and R134a, making it a versatile staple for most commercial HVACR applications. The 009G0242 model, which is functionally identical to the 009G024200, is built to withstand high working pressures and temperature fluctuations, providing a durable solution for flow control. For technicians looking for a reliable refrigeration isolation valve, this Danfoss unit offers low pressure drop and high-integrity seating, ensuring the system maintains peak efficiency during operation.

Key Benefits

• Hermetic Diaphragm Design: Provides a high-integrity seal to prevent refrigerant leakage and atmospheric contamination.
• Wide Refrigerant Compatibility: Suitable for modern HCFC and HFC refrigerants, allowing for consolidated inventory.
• Durable Brass Construction: Offers excellent corrosion resistance and structural integrity for long-term installation.
• Low Pressure Drop: Optimized internal flow path ensures minimal impact on system performance and energy consumption.
• Easy Installation: The 1/2" ODF solder connections allow for standard brazing techniques into existing copper lines.

Common Questions

What is the maximum working pressure for the Danfoss BML 12s?
This valve is typically rated for a Maximum Working Pressure (MWP) of 406 psig (28 bar), making it suitable for most standard high-pressure refrigeration cycles.

Is the Danfoss 009G0242 bi-directional?
While functionally capable of stopping flow, it is standard practice to install these valves in the direction of the flow arrow to ensure the diaphragm seats correctly under pressure.

Can this valve be used in CO2 (R744) systems?
The BML series is primarily designed for fluorinated refrigerants. For high-pressure CO2 applications, a valve specifically rated for transcritical or subcritical R744 pressures is required.
