Clapets anti-retour pour la climatisation et la réfrigération commerciales

Check valves are used to control one-way refrigerant flow and help prevent backflow in refrigeration and air conditioning systems. In cold room applications, they support reliable flow control in liquid, suction, and hot gas lines, helping the system operate as intended.

Features and benefits

Controls one-way refrigerant flow to help prevent backflow
Relevant for cold room systems as well as broader refrigeration and air conditioning applications
Suitable for liquid, suction, and hot gas lines
Supports fluorinated refrigerants, hydrocarbns and CO₂
Available in straightway and angleway versions
Offered with flare and solder connections, including oversize connection options to fit to larger pipe diameters
Includes variants for different system needs, including systems with compressors in parallel and CO₂ applications
Designed with low pressure drop during operation and a built-in damping piston for lines where pulsation can occur
NRVH for discharge line location in paralle compressor arrangements surpresses flattering caused by compressor pulsations

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
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
Les clapets anti-retour NRV 10s H pour R744 (CO2) peuvent fonctionner comme une soupape de décharge interne lorsqu'ils sont installés en parallèle avec des vannes à bille GBC ou des vannes d'arrêt de service, à l'entrée et à la sortie des composants à entretenir. Le NRV 10s H peut également être utilisé dans les lignes de dégivrage au gaz chaud.
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 CO₂systems such as hot gas and suction lines.
