Four-way valve assembly is integrated by four-way valve and pipe assembly to simplify the client welding work. lt switches cooling or heating function of air conditioning by changing the flow path of refrigerant
FEATURES：
Maximum Working Pressure：4.5Mpa
Medium Temperature：-40℃~130℃
Applicable Refrigerants：R410A、R32、R134a、R404A、R507、R290、R407C、R22
Purpose: Four-way valve assembly is integrated by four-way valve and pipe assembly to simplify the client welding work. lt switches cooling or heating function of air conditioning by changing the flow path of refrigerant
FEATURES:
1、The whole process of product welding is protected by flowing water whose temperature maintains below 50°C to ensure product works stead
2、High and Low Voltage Reversal Detection is implemented to ensure four-way valve assembly works steady
3、Four-way valve assembly produces specialized tools based on the compressor dimensions to match
4、The temperature detection accuracy is improved based on DunAn' s patent
