Danfoss SVA-S 20 Shut-off Valve | Steel, Angled | 148B5311
Product Description:
The Danfoss SVA-S 20 (148B5311) is a specialized angled shut-off valve designed for the demanding requirements of industrial cooling plants in the UAE. Constructed from high-quality, low-temperature steel, this valve is optimized for use with Ammonia ($NH_3$), $CO_2$, and other common refrigerants. The SVA-S series is renowned for its “Standard” neck length and superior flow characteristics, which minimize pressure drop—a vital factor for system efficiency in Dubai’s large-scale refrigeration racks. With a maximum working pressure of 754 psig, it is perfectly suited for modern high-pressure installations. Its internal sealing design and moisture-resistant internal components ensure a long, leak-free service life even when exposed to the intense ambient heat and high humidity characteristic of the UAE coastal climate.
Key Features & Benefits:
- High Pressure Capability: Rated for 754 psig (52 bar), making it an ideal choice for both traditional and high-pressure $CO_2$ systems in the UAE.
- Superior Sealing Integrity: Features a specialized back-seating function that allows the stem seal to be replaced even while the valve is under pressure in UAE field operations.
- Optimized Flow Dynamics: The angled body design ensures high flow capacity with minimal resistance, reducing energy costs for Dubai industrial facilities.
- Climate-Resistant Steel: Built with high-grade steel that maintains mechanical strength in the extreme temperature fluctuations of the UAE.
- Universal Refrigerant Use: Fully compatible with Ammonia, HFCs, and HCFCs, providing a versatile solution for varied cooling applications across the UAE.
