Series TBE

THERMOSTATIC EXPANSION VALVESFIXED ORIFICE, FLARE CONNECTIONS

PRODUCT DATA

Features

TBE: with internal pressure equalisation; for singleinjection in installations with one or more coolingcircuits. TBEX: with external pressure equalisation; for optimalevaporation effectiveness in all applications.Obligatory for multiple injection by liquid distributors. Combi adsorber charge as standard. The same valvecan be used for different refrigerants (see table on page 2) Controller charge is high sensitive and responsivethus lowest possible level of superheat can beachieved Charge is not sensitive to effects of temperature onthe capillary tube and valve head TBEX 0.5 - 4.5 two-wayTBEX 0.5 - 4.5 angle damping characteristic results in stable control behaviour Optional available with gas charge and MOP Adjustable superheat for two-way construction Fixed superheat setting for angle construction Warm thermal head provides best reliability Flare connections Extreme durable due to stainless steel head andstainless steel diaphragm welded using protective gas

Application

Fixed orifice Thermostatic expansion valves series TBE are used in plantswith one or more refrigerant circuits, especially for seriesinstallations mobile air-conditioning and cooling units withflare connection, e. g. bus AC, train AC, transport cooling. Refrigerants:R134a, R401A, R12R22, R407C, R407AR404A, R507, R402A, R407B, R502Further refrigerants on request.
