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.
Features and benefits
- Available in both straightway and angleway versions which is easy to connect
- Hermetic tight design for solder versions with low risk of external leakage
- 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
- 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
- Low pressure drop during operation
- Oversize connections provide flexibility in use
