Product Details

HVAC condensing pressure regulator KVR NRD Series for pressure testing
 
 
KVR + NRD pressure regulation system for the use of air-cooled condenser refrigeration and air-conditioning devices to maintain a constant and high enough to the condenser pressure and reservoir pressure;
KVR can be used with the KVD type accumulator pressure regulator

 
Product Features:
1. To achieve precise and variable pressure regulation, 1 / 4in.Schrader valve for pressure testing
2. Cooling capacity and operating range
3. Pulsation damping design, stainless steel bellows
4. Muscle angle form of the design, easy to install in any location
5. "closed" brazing structure, providing a wide range of size of the bell mouth and outer diameter welding interface
6. Can be used for CFC, HCFC and HFC refrigerants

 
TECHNICAL GUIDE
Refrigerant valve within the scope of the CFC, HCFC, HFC adjustment range of 5 ~ 17.5bar
Factory setting = 10 bar Maximum operating pressure KVR: BP = 28 bar NRD: BP = 28 bar
Maximum test pressure KVR: p '= 31 bar NRD: p' = 36 bar Medium maximum temperature KVR: 105 ° C NRD: 130 ° C
Minimum temperature of the medium: -40 ° C P bandKVR 12 to 22: = 6.2 bar KVR 28 to 35: 5 bar
The opening differential pressure is used to start the NRD opening: Δp = 1.4 bar full open: △ p = 3 bar

 
Condensing pressure regulator
 
Refrigerant: R22/R134A/R507
 
Regular 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.
