4-Way Reversing Valve DSF Series


The DSF series 4-way reversing valve is applicable to all kinds of heat pump systems. It changes the flow path of refrigerants by controlling the pilot valve to switch the mode between cooling and heating.


Thermoset material molded electromagnetic coil, better water resistance, greater electric strength, and more reliable insulation;

Energy-saving bi-stable series has less temperature rise, lower noise, and slighter vibration;

and more environmentally friendly manufacturing processes, and is manufactured in a more environmentally friendly process.
