Four-Way Valve Assembly
FEATURES

● The whole process of product welding is protected by flowing water whose temperature maintains below 50℃ to ensure product works stead

● High and Low Voltage Reversal Detection is implemented to ensure four-way valve assembly works steady

● Four-way valve assembly produces specialized tools based on the compressor dimensions to match 

● The temperature detection accuracy is improved based on DunAn's patent

TECHNICAL PARAMETERS

● 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. It switches cooling or heating function of air conditioning by changing the flow path of refrigerant
