Carrier 319073-201 Piston Retainer

The Carrier 319073-201 Piston Retainer is a small but essential part of Carrier HVAC systems, which are used in metering devices of air conditioners and heat pumps. In its simplest sense, the activity of a piston retainer is to effectively position the piston and ensure that right and appropriate flow of refrigerant is achieved across the structure. The piston retainer increases the rate in cooling and heating by controlling the refrigerant in the system with no fluctuations in performance and reduction of energy consumption.
