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.

FEATURES

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
