and cooling model conversion. It consists of main valve, pilot valve and solenoid valve, existing among refrigerant circuit of compressor, condenser, indoor & outdoor heat exchanger. It revert heating and cooling system through controlling of main body by pilot valve, taking action by differential pressure. Then reversing the flow direction of cooling and heating system. It is convenient and reliable, suitable for heat pump system , used at central, unit and room air condition.
It consists of three series:
DSF-09A(R22)/ DSF-09B(R407C)/DSF-09(R410A) with coil 450mm
