Danfoss GBC 12s Shut-off Ball Valve | 1/2 in Solder ODF | 009L7052
Product Description:
The GBC 12s (009L7052) is engineered for maximum system efficiency. In the UAE—where cooling systems are often pushed to their limits—this ball valve ensures minimal pressure drop, which is critical for maintaining performance in the intense Middle Eastern heat. The valve is designed with a laser-welded body to prevent refrigerant leaks and features a rupture-proof stem for maximum technician safety. The 1/2 inch ODF solder connections allow for a permanent, high-integrity brazed joint, commonly used in the liquid and suction lines of split AC units, commercial chillers, and cold storage systems in Dubai and Abu Dhabi.
Key Features & Benefits:
- Full Flow Bore: Designed for maximum flow with negligible pressure drop, optimizing the energy efficiency of the refrigeration cycle.
- Hermetically Sealed: Laser-welded construction eliminates leak paths, ensuring environmental compliance and reducing refrigerant loss.
- 45 Bar Working Pressure: Fully compatible with high-pressure refrigerants like R410A and R32, which are standard in modern UAE HVAC installations.
- Bi-directional Capability: Can be installed in any orientation, providing maximum flexibility for UAE contractors in tight equipment spaces.
- Safety Lock Cap: Includes a robust seal cap that complies with safety regulations and prevents accidental adjustment or leakage from the stem.

FAQs:
- Q: Is it safe to braze this valve directly without disassembly?
- A: Yes, the GBC 12s is designed to be brazed without disassembly, but it is critical to use a wet cloth to cool the valve body and prevent internal seal damage during the brazing process in the UAE heat.
- Q: Does it indicate the open/closed status?
- A: Yes, the top of the valve stem has a slot that indicates the direction of the internal ball port, showing whether the valve is open or closed.
- Q: Can this handle hot gas defrost lines?
- A: Absolutely. With a temperature rating of up to 150°C, it is perfectly suited for hot gas lines and discharge applications.
