Application fields
The control valve with four nozzles is an indispensable component in the refrigeration equipment. Its working principle is that when the solenoid valve coil is in the power-off state, the exhaust pipe is connected with the connecting pipe of the outdoor unit, and the other two connecting pipes are connected to form a refrigeration cycle; When the solenoid valve coil is energized, the exhaust pipe is connected with the connecting pipe of the indoor unit, and the other two connecting pipes are connected to form a heating cycle
