Zawory zwrotne do klimatyzacji komercyjnej i chłodnictwa

BCV

FCV

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

Zawory zwrotne NRV 10s H dla R744 (CO2) mogą działać jako wewnętrzny zawór bezpieczeństwa, gdy są zainstalowane równolegle z zaworami kulowymi GBC lub zaworami odcinającymi na wlocie i wylocie komponentów do serwisowania. NRV 10s H może być również używany w liniach odszraniania gorącym gazem.

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 CO₂ systems such as hot gas and suction lines.
