Danfoss 020B1018 Check Valve
The Danfoss 020B1018 is a high-performance NRV 16S check valve engineered specifically for technical applications in refrigeration and air conditioning systems. This piston-design valve features 5/8" ODF solder connections and a straightway body construction, making it an essential component for preventing backflow and cross-condensation in liquid lines, suction lines, and hot gas lines. With a maximum working pressure of 710 psig (49 bar) and a broad operating temperature range of -58°F to +284°F, it is fully compatible with modern HFC, HCFC, and HC flammable refrigerants, including R410A, R22, and R134a. The integrated damping piston is a critical feature for contractors, as it effectively handles high-frequency pulsations often found in compressor discharge lines, ensuring steady operation and preventing premature wear. This HVACR check valve provides a reliable seal with a minimum pressure drop of 0.7 psi, optimizing energy efficiency and system performance across commercial and industrial cooling plants.
Key Benefits- Refrigerant Versatility: Certified for use with a wide range of fluids, including R410A, R448A, R449A, and R290, ensuring project compatibility.
- Pulsation Damping: Features a built-in piston design that mitigates vibration and noise in high-stress discharge line applications.
- Hermetic Reliability: The copper ODF solder connections provide a leak-proof, hermetically sealed interface for long-term system integrity.
- Low Pressure Drop: Optimized internal geometry ensures maximum flow capacity (Cv value of 4.67) while maintaining minimal resistance.
- Durable Construction: Built with a robust brass body to withstand harsh environmental conditions and high-temperature thermal cycling.
Can the NRV 16S be installed in any orientation?
This straightway valve is designed for specific flow directions; always verify the flow direction indicator on the product label during installation to ensure proper check functionality.
Is this valve suitable for oil-free systems?
Yes, the Danfoss 020B1018 is compatible with oil-free applications and various lubricant types used in modern HVACR setups.
Will this check valve prevent back-condensation?
Correct. When installed between the condenser and evaporator, it prevents refrigerant from migrating back to the cold evaporator during the off-cycle.
