Product Description Product Description The KVR+NRD pressure regulating system is used to maintain constant and sufficiently high condenser pressure and receiver pressure in refrigeration and air conditioning installations with air-cooled condensers.KVR can be used with KVD type reservoir pressure regulatorFeatures-Realize precise and variable pressure regulation-Wide application refrigeration capacity and operating range-Pulsation damping design-Stainless steel bellows-Compact angled design, easy to install in any location-1/4.Schrader valve for pressure testing-Provide bell mouth interface and outer diameter welding interface in a wide range of sizes-"sealed" brazed structure-Can be used for CFC, HCFC, HFC refrigerantsTechnical ParametersAdjustment range: 5~17.5bar Factory setting 10bar Maximum medium temperature: KVR: 105oC NRD: 130oCMaximum working pressure: KVR: BP=28bar NRD: BP=28bar Minimum medium temperature: -40oCMaximum test pressure: KVR: p'=31bar NRD: p'=36barP bandKVR12~22:=6.2bar KCR28~35:=5barOpening pressure differential for NRD Start opening: Δp=1.4bar Full opening: Δp=3barTYPENominal liquid load Δp=0.2bar (evaporator load) kwHot gas load Δp=0.2bar (evaporator load) kwBell mouth connectionProduct CodeSolder connectionProduct CodeR22R134aR407A/R507R4C7CR22R134aR404A/R507R407Cin.mmin.mmKVR1250.447.336.654.413.211.61214.31/212034L00911/2 034L0093 12034L0096KVR155/816034L00925/816034L0097KVR22 7/822034L0094KVR2812912193.7139.334.930.634.937.7 1? 034L0095 28034L0099KVR351?35034L0100NRD 1/2 020-1132 12020-1136te=-10oC tc=+30oCKVR type regulator is supplied without bell nutbell nut1/212011L1103 5/816011L1167When the gas flow velocity at the regulator inlet exceeds 40m/s, flow noise will occur. Therefore, the interface size of the regulator cannot be chosen too small. Company Profile
