Danfoss EVR 20 Solenoid Valve | Normally Closed (NC) | 7/8 in ODF Solder

Product Description:

The Danfoss EVR 20 (032L1240) is engineered to meet the high-capacity demands of mid-sized cooling systems across the UAE. As a servo-operated valve, it ensures smooth and efficient modulation of refrigerant in liquid, suction, and hot gas lines, minimizing pressure drops even during Dubai’s peak summer loads. Its 7/8 in ODF solder connections are precision-built to provide a permanent, hermetic seal, which is vital for system integrity in the Middle East’s high-ambient environments. Constructed with high-grade materials, the EVR 20 offers a reliable “fail-safe” shut-off when de-energized, protecting compressors and optimizing overall system efficiency in various UAE commercial applications, from retail cold storage to central AC units.

Key Features & Benefits:

• Reliable Flow Control: Optimized internal porting handles high mass flows with low pressure drop, enhancing the EER of UAE cooling systems.
• Positive Shut-off (NC): Normally Closed design provides instant refrigerant isolation upon power loss, a critical safety feature for Dubai facilities.
• Hermetic Solder Integrity: 7/8 inch ODF connections ensure a leak-proof, vibration-resistant joint for UAE HVAC installations.
• High Working Pressure: Rated for up to 45.2 bar, making it fully compatible with R410A and other high-pressure refrigerants used in the UAE.
• Durable Build Quality: Engineered to withstand the thermal stress and corrosive saline air typical of UAE coastal developments.
