【Use】
DPF electronic expansion valve is mainly used in the variable frequency air conditioning system to realize the automatic regulation of refrigerant flow, and finally make the air conditioning system according to the change of load to achieve the best refrigeration/heat production, the most accurate temperature and energy saving effect.
【Explain】
◇When connecting and welding with the main engine, it should remove the coil firstly, cool the valve body with water or wet cloth, so that the temperature of the valve body does not exceed 120℃
◇recommended installation: vertical valve body, coil up.
