REFRIGERATION CHECK VALVE
Egret BL-DXF series Diaphragm check valve adopts a magnetic, diaphragm, filter self-priming structure design so that the check valve is not limited by the installation Angle and the relationship between the size of the reverse pressure to affect the automatic closure of the valve. It has advantages such as very small flow resistance, high volume of flow, minimum internal leakage, and a lifetime of over 10 million times. Important to realize, it is suitable for all refrigerants and large and medium heat pump central air conditioning system built-in filter. In order to make sure the normal closure of the valve, the built-in filter screen is 30 meshes.

Features of Refrigeration Check Valve
Self-suction filter structure design
Automatically closed, not affected by reverse pressures
Less flow resistance
Bigger flow volume
Less internal leakage

Process of Refrigeration Check Valve Production
The process of refrigeration check valve is not complicated. First, we use turning lathe and CNC milling machine, to cutting and machining different size of stainless-steel diaphragms.
Second, melting the copper material, and pour the melting copper into the copper casting mold to produce the magnetic check valve body, copper tube.
Third, to make magnetic with the raw materials such as praseodymium neodymium, pure iron and iron borate are melted at high temperature by vacuum melting furnace.
Forth, use argon arc welding method, to assembling Mesh filter, magnetic, diaphragm, copper tube.
Fifth, use PTFE sealing method and the copper sealing cap to make sure airtight.
