YORK Expansion Valve Coil S434

The YORK Expansion Valve Coil is high quality!The electronic expansion valve generates a magnetic field by the coil through the current and is used as the valve needle to drive the valve needle to rotate. When the positive and negative power voltage and signal of the coil are changed, the electronic expansion valve will also be opened, closed or change the size of the opening and closing gap, so as to control the flow of refrigerant and the size of refrigeration and heat in the system. The smaller the spool is opened, the smaller the refrigerant flow, and the greater the refrigeration and heat.
