Danfoss EVR 20 Solenoid Valve | 1 1/8 in Solder ODF | 032L1244

Product Description: The EVR 20 (032L1244) is designed for systems that require significant refrigerant mass flow. In the UAE’s intensive cooling market—specifically for large-scale supermarket racks, industrial chillers, and warehouse cold storage—this valve provides reliable control for liquid, suction, and hot gas lines. The $1\ 1/8$ inch ODF solder connections ensure a permanent, leak-proof bond capable of withstanding the high operating pressures and vibrations common in Dubai and Abu Dhabi’s heavy-duty machinery rooms. Its “Normally Closed” design ensures the valve remains shut when de-energized, facilitating safe pump-down cycles and protecting the compressor from liquid slugging.

Key Features & Benefits:

• High-Volume Flow: Optimized for larger systems, delivering a $K_v$ value of $5.0\ m^3/h$ to meet the demands of high-capacity UAE cooling plants.
• Normally Closed (NC) Safety: Provides a secure shut-off when power is removed, ensuring system safety during standby or power failure.
• Leak-Proof Solder Interface: The $1\ 1/8$ inch ODF connections are built for high-integrity permanent joints, vital for maintaining refrigerant charge in the UAE’s harsh climate.
• Broad Refrigerant Range: Compatible with all common HFC/HCFC refrigerants and high-pressure refrigerants like R410A.
• Durable in High Ambients: Engineered to maintain peak performance even in the high temperatures found in Middle Eastern mechanical rooms.

FAQs:

• Q: Can the EVR 20 032L1244 be used for hot gas defrost in Dubai?
• A: Yes, its high-temperature rating (up to 105°C) makes it ideal for hot gas bypass and defrosting applications in large refrigeration systems.
• Q: Does this valve require a minimum pressure to operate?
• A: Yes, as a servo-operated valve, it requires a minimum differential pressure (typically 0.05 bar) to open and stay open.
• Q: Is the coil included?
• A: No, the 032L1244 is the valve body only. It is compatible with Danfoss 10W or 12W “Clip-on” coils, widely available in the UAE.
