Check valves for Commercial A/C and Refrigeration

Optimized for use in liquid, suction and hot gas lines

The Danfoss NRV and NRVH check valves are optimized for use in liquid, suction and hot gas lines in air conditioning applications to ensure correct flow direction. The NRVH valve is especially designed for systems where compressors are connected in parallel.

 

Features and benefits

  • The valves can be used for fluorinated refrigerants as well as CO2

  • Straightway and angleway versions are available

  • Supplied with flare and solder connections

  • Available with oversize connections for easy installation

  • NRVH is supplied with spring to Δp = 0.3 bar (4 psi)

  • NRD category image

    NRD

    Regulating system KVR and NRD is used to maintain a constant and sufficiently high condenser and receiver pressure in refrigeration and air conditioning plant with air-cooled condensers. KVR can also be used together with receiver pressure regulator, type KVD.

  • NRV / NRVH category image

    NRV / NRVH

    NRV and NRVH piston type check valves are designed for installation in commercial refrigerating systems and in residential or industrial air conditioning plants. They are used to control the unidirectional flow of refrigerant so as to prevent backflow.

  • NRV 10s H category image

    NRV 10s H

    NRV 10s H check valves for R744 (CO2) can work as an internal relief valve when installed in parallel with GBC Ball Valves or service shut off valves, at the inlet and outlet of components to be serviced. The NRV 10s H can also be used in hot gas defrosting lines.

  • NRVT category image

    NRVT

    NRVT piston type check valves is designed for installation in discharge line to prevent refrigerant migration to protect compressor and enable the pressure equalization of rotary compressor before startup. In the meanwhile, this valve can be used in other installation positions of CO2 systems such as hot gas and suction lines.
