Quick Response Expansion Valve and Precision Superheat Controller, 01 Firmware Version, R427A Refrigerant Type, Individual Packaging

The Quick Response Expansion Valve (QREV) with the Precision Superheat Controller (PSHC) is a compact, electronic, closed loop, rapid response superheat control solution for refrigeration and HVAC applications. The QREV is next generation electronic expansion valve (EEV) technology, providing maximum evaporator efficiency by quickly reaching the preferred superheat. The QREV includes a silicon-based microelectromechanical system (MEMS) pilot valve that responds to a signal from the PSHC and pilots a smooth gliding spool valve that regulates refrigerant flow through the QREV, virtually eliminating valve wear and greatly extending valve life. The PSHC is an electronic superheat controller that provides precise control to the QREV through varying load conditions. The PSHC uses an internal pressure sensor and an external temperature sensor to control the QREV flow and maintain the preferred superheat at the evaporator outlet. Refer to the Quick Response Expansion Valve and Precision Superheat Controller Product Bulletin (LIT-12012398) for important product application information.
