Danfoss 020-1040 Check Valve
The Danfoss 020-1040 is a high-performance NRV 6 check valve designed to maintain unidirectional refrigerant flow and prevent back-condensation in liquid, suction, and hot gas lines. Featuring a 1/4" flare connection, this straightway piston-type valve is engineered for durability in demanding commercial refrigeration and HVACR systems. It utilizes a built-in damping piston, making it an ideal choice for installation in lines where pulsation is frequent, such as compressor discharge lines. With a maximum working pressure of 667 psig (46 bar) and an expansive operating temperature range from -58°F to 285°F, the Danfoss 020-1040 provides consistent reliability across various fluorinated refrigerants and oil-free applications. Its brass body construction and precision-machined internals ensure a low pressure drop while protecting critical system components from reverse flow damage. For technicians seeking a robust non-return valve, this Danfoss refrigeration part offers the specialized dampening required for high-vibration environments.
Key Benefits:- Pulsation Dampening: Integrated damping piston allows for stable performance in high-pulsation discharge lines.
- Broad Compatibility: Fully compatible with a wide array of refrigerants including R404A, R134a, R410A, and R513A.
- High Pressure Rating: Engineered to handle maximum operating pressures up to 46 bar, suitable for modern high-pressure systems.
- Universal Application: Versatile design allows for deployment in liquid, suction, or hot gas lines to ensure refrigerant flow control.
- Leak-Proof Connection: The 1/4" flare male-to-male connection ensures a secure, mechanical fit without the need for brazing.
Can this valve be installed in any orientation?
The Danfoss NRV 6 is a straightway valve that must be installed according to the flow direction indicator on the product label to ensure the non-return piston functions correctly.
Is the 020-1040 suitable for parallel compressor racks?
While the 020-1040 is highly effective for standard systems, for parallel configurations with extreme vibration, some contractors prefer the NRVH version with a stronger spring. This standard NRV is optimized for the lowest possible pressure drop in most commercial layouts.
Does this valve require a flare nut for installation?
The Danfoss 020-1040 features 1/4" male flare connections. Standard flare nuts are required but are generally sold separately or repurposed from existing piping.
