Danfoss GBC 79s Shut-off Ball Valve | 3 1/8 in (79 mm) ODF Solder | 009L7981
Product Description:
The Danfoss GBC 79s (009L7981) is designed for the most demanding high-flow applications across the UAE. Featuring 3 1/8 in (79 mm) ODF solder connections, it provides a permanent, high-integrity joint for the massive liquid and suction lines found in Dubai’s mega-malls and district cooling plants. Its full-bore construction ensures a completely unrestricted flow path, which is vital for minimizing energy loss and maintaining high COP in the intense UAE summer heat. Rated for 45 bar, it is compatible with all modern refrigerants and features a robust dual-sealing system and a blow-out proof spindle for maximum operator safety. This valve is the pinnacle of reliability for large-scale UAE infrastructure projects where downtime is not an option.
Key Features & Benefits:
- Extreme Full-Bore Flow: Unrestricted flow path with an immense Kv value, optimized for the high-capacity needs of UAE cooling systems.
- Heavy-Duty Solder Ports: 3 1/8 inch ODF connections ensure a secure, hermetic brazed joint for the largest UAE piping headers.
- 45 Bar Industrial Rating: Built to handle the high pressures of HFC and HCFC refrigerants used throughout Dubai and Abu Dhabi.
- Safety Lock Cap: Includes a robust seal cap to prevent accidental leaks or unauthorized operation in UAE plant rooms.
- Bi-Directional Flexibility: Can be installed in any orientation, allowing for easy placement in complex UAE mechanical room layouts.
