PWM 2028 THE PULSING PART OF THE CIRCUIT

The synergy of the expansion valve with all the components characterizes the refrigeration circuit, and makes it possible to maintain constant performance through all climatic changes throughout the year. The series 2028 valves are a throttling device that receives liquid from the condenser and injects it into the evaporator, creating the necessary pressure drop across the expansion orifice. The valve can guarantee a hermetic seal when it is in the closed position, It also functions as a normally closed solenoid valve. This means you can install this valve in the system as the only valve in the liquid line before the evaporator, you can remove the standard solenoid valve. Simplicity and safety are the major qualities that distinguish this expansion valve, capable of operating up to 90 bar, as well as being able to operate with all kinds of refrigerants and with a differential pressure above 40 bar.
