air conditioning four way valve 

Good thermal conductivity and thermal expansion  Copper This metal has excellent thermal conductivity, higher than cast iron and stainless steel. Therefore, the copper valve can transfer heat to the outside environment more quickly, thereby preventing the temperature from rising too fast, resulting in pipeline rupture, which greatly increases the stability of the valve. At the same time, the coefficient of thermal expansion of copper matches well with the temperature change of the fluid, which can reduce the thermal stress of the valve when the temperature changes and extend the service life. Air Conditioner Parts include:Ac Heat Exchanger Valve 4 Way,Air Conditioner Copper Pipe,Copper Tube,Copper Capillary Tube.
