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 regulator

Features

-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 refrigerants
