Thermal Expansion Valves
Features
• Stainless steel power element eliminates corrosion and
prevents valve failure
• Replaceable power element
• External superheat adjustment
• ODF connections
• Balanced port construction compensates for changes in
operating pressures due to varying ambients, or widely
varying evaporator loads
• Bi-Directional control capacity
• External equalizer
Specifications
• Maximum working pressure: 450 psig
The TFE R-22 series is designed for large tonnage heat pump,
air conditioning, and commercial refrigeration applications.
