Danfoss Check Valve
With Danfoss thermostatic expansion valves, you can expect precise operation and long service life of your refrigeration system. The valves control the injection of liquid refrigerant into evaporators and protect the compressor motor against liquid refrigerant. The thermostatic expansion valve allows you to keep a constant superheat (or refrigerant level) at varying load situations in the refrigeration system to save energy.
Available in both straightway and angleway versions which is easy to connect
Hermetic tight design for solder versions with low risk of external leakage
NRVH type check valve is with stronger spring and it's recommended to use for compressors in parallel (i.e. power packs) where higher level of pulsation and vibration are expected
Built-in damping piston that makes the valves suitable for installation in lines where pulsation can occur, e.g. in the discharge line from the compressor
Compressor crankcase heater, oil separator, check valve, oil return line, vibration eliminator, dual pressure switch, pressure gauges.
