CBX Bypass valve

Model:
Price:0US$

General

l   The CBX discharge-bypass valve is a kind of load adjust component for the refrigerating system with a non-adjustable compressor.

l   The CBX discharge-bypass valve can be used as automatic expansion valve under fixed pressure to maintain the fixed evaporation pressure (temperature).

l   The CBX discharge-bypass valve is capable of maintaining the minimum evaporating pressure.

l   ODF connecting.

l   Suitable for HFC and HCFC.

l   Maximum working pressure: 28bar.

 Details

Function

The CBX discharge-bypass valve can automatically change the opening to get  the constant outlet pressure on regardless of the change of the inlet pressure (within a certain range). 

 

CBX used as expansion valve under the fixed pressure

If the inlet of the CBX discharge-bypass valve is connected to the condenser and outlet to the evaporator, that is, on the normal position of thermal expansion valve ,the CBX valve is closed when system turning off due to higher evaporating pressure; and it will open automatically after compressor on due to evaporation pressure decreasing. The refrigerant flows into the evaporator through the throttling hole of CBX. After the evaporator absorbs heat, the increasing evaporating pressure makes the valve closed. Once again, operation of the compressor makes evaporating pressure decreased and the valve turns to open status. During the operation, the valve always keeps the dynamic balance, maintaining the evaporating pressure constant approximately at the setting point. The variation situation of the evaporating pressure has something to do with the volume of the valve, regardless of the condensation pressure (or environment temperature).
