Danfoss Check Valves

Danfoss one way valve

Danfoss HVAC check valve

Danfoss non return valve

clack valve

non return valve

one way valve

NRV and NRVH check valve can be used as fluoride refrigerant refrigeration and air conditioning devices, liquid, suction and hot gas on the road.

 

NRV and NRVH check valves provide extra-large connections to increase the flexibility of check valve applications

 

Product Features:

◆ This valve ensures the only correct flow direction

◆ There are two types of direct and angle valve

◆ prevent the refrigerant from the high-temperature evaporator to the low-temperature evaporator back

◆ Built-in damping piston, so that check valve can be installed in a place where the pressure pulse, such as the compressor exhaust pipe

◆ NRVH with △ p = 0.3bar to strengthen the spring, the compressor used in the parallel cooling device

◆ large size connection, providing the flexibility of the application
 

Technical Parameters:

The maximum working pressure PB = 46bar

The maximum test pressure p '= 60 bar

Medium temperature -50 ~ 140 ℃
Quick Selection:

Valve installed in the hot air pipe, through the maximum pressure drop valve is 1bar

 

NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with fluorinated refrigerants. NRV and NRVH can be supplied with flare and solder connections. They are also available with oversize solder connections providing flexibility in the use of check valves.

Product Features

NRV

Copper solder connections

Straightway

Max. Working pressure = 46 bar. Max. test pressure = 60 bar. Temperature of the medium: -50 - +140°C

NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plant with fluorinated refrigerants.

NRV and NRVH can also be supplied with oversize connections providing flexibility in the use of check valves.

Features

The valve ensures only correct flow direction

Both straightway and angle way version

Prevents back-condensation from warm to cold evaporator

Built-in damping piston

That makes the valves suitable for

Installation in lines where pulsation can occur, e. G. In the discharge line from the

Compressor.

 

NRVH is supplied with spring to

P = 0.3 bar.

Used in refrigeration plant with compressors connected in parallel.
Oversize connections provide flexibility in use.
Technical data
Max. Working pressure

PB = 28 bar

Max. Test pressure

P' = 36, 4 bar

Temperature of the medium

50 140 C

Dimensioning and selection

When dimensioning and selecting check valves to be mounted into the compressor discharge line, it is important to be aware of the following:

The differential pressure across the check valve must always be higher than the given

Minimum pressure drop at which the valve is completely open. This also applies to lowest capacities for compressors with capacity

Regulation.

In refrigeration plant with compressors connected in parallel, it is advantageous to use NRVH equipped with a stronger spring than NRV.

With check valve, type NRVH, resonance problems can be avoided at partial load in the Refrigeration plant. The differential pressure across NRVH at partial load must not be lower than minimum pressure drop for NRVH
with completely open valve.

 

CCV check valves are suitable for liquid lines, suction lines and hot gas lines for refrigerating, refrigerating and air conditioning units using fluoride refrigerants.

 

Product use: to prevent the media back, to prevent the pump and drive motor reverse and the container media release

 

Application: suitable for the use of fluoride refrigerant refrigeration and air-conditioning devices, liquid, suction and hot gas on the pipeline

 

Product Features:

1. Fully sealed construction

2. Magnetic valve design

3.100% copper, easy to weld

 

FEATURES

• Suitable for HCFC and non-combustible HFC refrigerants

• Fully enclosed construction

• Magnetic valve design

• 100% copper tube for welding

• CCV complies with China Machinery Industry Standard (JB / T)

• Technical parameters • Maximum working pressure: 35bar

• Operating temperature range: -30 ℃ - +120 ℃
