Sanhua Thermostatic Expansion Valve (RFGD)

Thermostatic Expansion Valve Series RFGD

RFGD series thermostatic expansion valves are used to adjust the mass flow of refrigerant into the
evaporator while controlling the refrigerant superheat at the outlet of the evaporator. They can be used
for various refrigerants under all working conditions. Typical applications are refrigerations systems
like commercial refrigerators and freezers, icemakers, dehumidifiers as well as air conditioners at
various evaporation temperatures.

Features


 Compact design with built-in orifice
 Warm thermo head construction
 All connections pipes are completely in copper
 Valves with MOP function can be provided to assure reliable compressor operation
 Applicable to a wide evaporation temperature range
 Reliable and consistent performance of superheat control
 Balanced Port - suitable for reversible cycles
 Thermal bulb utilizes cross charge technology, providing consistent superheat degree over 
  the whole evaporation temperature range


General Specification

 Applicable for all common HCFC and HFC refrigerants such as : R22, R134a, R404A, R407C,
  R410A, R507

 Ambient temperature min./max. : -35oC/+55oC
 Medium temperature TS min./max. : -40oC/+70oC -60oC/+70oC
 Maximum operating pressure PS: 2,1 ... 4,5 Mpa (21...45 bar) 
 Maximum operating pressure is related to the used refrigerant
