T2 Thermostatic Expansion Valve
T 2 and TE 2 thermostatic expansion valves have an interchangeable orifice
assembly.
The orifice assembly is suitable for all versions of valve body and
refrigerants and in all evaporating temperature ranges. The charge in
the thermostatic element depends on the refrigerant and evaporating
temperature range. The valves are available with internal (T2) or external
(TE2) pressure equalization.
