QREV0224SCC

Together, the QREV with the PSHC kit forms an electronically controlled expansion valve that will maximize evaporator efficiency. It allows users to capture energy savings by reaching targeted superheat faster and controlling the valve more precisely, through varying load conditions. This unique silicon-based MEMS technology eliminates valve wear. There are no stepper motor failures associated with this type of technology. The PSHC comes loaded with any one of 17 approved refrigerants for easy commissioning, plus it has an on-board pressure sensor. The wiring harness, which completes the kit, includes a temperature sensor. This new product combination is easy to install, precise, fast and reliable.

• Fast, accurate control of refrigerant flow and superheat for maximum evaporator efficiency
• Silicon-based MEMS technology eliminates valve wear, extending life: no stepper motor failures
• Preconfigured PSHC reduces install and commissioning time
• Closed loop solution: no front-end controllers needed
• ModBus RTU: integrate into popular refrigeration control systems for remote visibility
• Power failure: valve closes with loss of power, protecting compressor from refrigerant flood back
• High durability, reliability
• Backed by a 3-year warranty

The QREV is next generation electronic expansion valve (EEV) technology, providing maximum evaporator efficiency by quickly reaching the preferred superheat. It includes a silicon-based micro electromechanical 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.

• MEMS based hybrid expansion valve for refrigeration and HVAC applications
• Compact footprint
• PWM signal control with quick response time (0.25 second for full stroke)
• Valve is refrigerant neutral (each valve can be used with any of 17 approved refrigerants)
• Direct TXV or EEV replacement
