User manual HONEYWELL TMVX

[. . . ] · TMVXX:Valve body and solder base with external pressure equalisation; for optimal evaporation effectiveness in all applications. Obligatory for multiple injection by liquid distributors. · Combi adsorber charge The same valve can be used for different refrigerants (see table on page 2) Controller charge is high sensitive and responsive thus lowest possible level of superheat can be achieved Charge is not sensitive to effects of temperature on the capillary tube and valve head Damping characteristic results in stable control behaviour · Suitable for systems with hot gas defrosting · Adjustable superheat setting · Solder connections · Solder base available in two-way construction and in angle construction · Extreme durable due to stainless steel head and stainless steel diaphragm welded using protective gas · Interchangeable orifice cartridges · Refrigerants: R134a, R401A, R12 R22, R407C, R407A, R422D R404A, R507A, R402A, R407B, R502 R124, R227, R410A Further refrigerants on request. TMVXX-W TMVXX-D Application Thermostatic expansion valves series TMVX are used in general refrigeration and for original equipment.

Superheat Adjustment In general the Honeywell valves should be installed with the factory setting for the used refrigerant unaltered. At combi adsorber valves the label on the capillary tube indicates how to adjust the adjusting spindle (with arrow for direction), depending on the refrigerant used. This correction of the adjustment is essential to ensure that the control performance of the valve is correct. The refrigerant used must be marked on the label. This superheat adjustment is calibrated for lowest superheating and optimum evaporator utilisation.
