DANFOSS CHECK VALVE NRV 16s (020-1059)

DANFOSS CHECK VALVE NRV 16S (020-1059) NRV and NRVH check valves can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with HCFC, HFC and HC flammable refrigerants. Special versions, with a max. working pressure of 90 bar / 1305 psig are available for CO2 applications. The valves ensure the correct low direction and prevent back-condensation from a warm part of the system to the cold evaporator. A built-in damping piston makes the valves suitable for installation in lines where pulsation can occur, e. g. in the discharge line from the compressor. Application: - Traditional refrigeration - Heat pump systems - Air conditioning units - Liquid coolers - Transport refrigeration - Resonance problems can be avoided at partial load in the refrigeration plant - Oversize connections provide ?exibility in use - Prevents back-condensation from warm to cold system part - Ensures correct ?ow direction - In refrigeration plants with compressors connected in parallel, it is advantageous to use NRVH, since the spring is stronger than in NRV - Available in both straightway and angleway versions 020-1059 Product name: Check Valve Type: NRV 16s Inlet size [in]: 3/4 in Inlet connection type: Solder, ODF Outlet size [in]: 3/4 in Outlet connection type: Solder, ODF Approval: C UL US LISTED EAC Body material: Brass Connection compliance: ANSI Soldering 3/4 in int.
