TBE Valve Datasheet

Product catalog summary
Application
Thermostatic expansion valves (TBE series) are designed for use in systems with one or more refrigerant circuits, particularly in mobile air-conditioning and cooling units such as those used in buses, trains, and transport cooling. They feature flare connections for easy installation.
Materials
The valve body and connections are made of brass, while the thermal head is constructed from stainless steel, ensuring durability and reliability.
Features
  • Internal and external pressure equalization options for optimal injection and evaporation effectiveness.
  • Combi adsorber charge allows use with various refrigerants, providing high sensitivity and responsive control.
  • Adjustable and fixed superheat settings available.
  • Warm thermal head design for enhanced reliability.
  • Compatible with refrigerants such as R134a, R22, R407C, R404A, and others.
Specifications
  • Nominal capacity range: 1 to 16 kW.
  • Evaporating temperature range: varies by refrigerant.
  • Maximum pressure: 29 bar; test pressure: 32 bar.
  • Maximum ambient temperature: 100°C; bulb temperature: 140°C.
  • Static superheat: approximately 3 K.
  • Capillary tube length: 1.5 m; bulb diameter: 12 mm.
Thermal Charges and Temperature Ranges
  • Adsorber charge is insensitive to temperature effects on the capillary tube and valve head, reacting only to bulb temperature.
  • Pressure limiting performance (MOP) available for specific refrigerants.
Capacities
Capacities are provided for various refrigerants and orifice sizes, with specific values for R134a, R22, R407C, R404A, and R507.
Dimensions and Weights
Details on connections, dimensions, and weights for two-way and angle constructions are provided, with specific UNF thread sizes.
Superheat Adjustment
Factory settings are recommended, but adjustments can be made by turning the adjusting spindle. Clockwise turns reduce refrigerant flow and increase superheat, while counterclockwise turns have the opposite effect.
Installation
  • Valves can be installed in any position.
  • External pressure equalizer line should be connected downstream of the remote bulb.
  • Bulbs should be insulated and positioned correctly to avoid ambient temperature effects.
  • Flare nuts should be tightened carefully to avoid damaging the bulb.
Customization
The TBE series can be customized for specific equipment requirements. Contact Honeywell for more information.
