To avoid charge migration when using MOP
valves, the bulb temperature must always be
lower than the thermostatic element temperature.
Main valve data is indicated on the valve element
(g. 1), on the valve body (g. 2) and on the
bottom of the orice assembly (g. 3).
Example valve body
TUAE = Type (E = external equalization)
068U2214 = Code number
R134a = Refrigerant
MOP 55 / +15°C = MOP-point in psig / °C
−40 /+10°C = Evaporating temperature
range in °C
−40 /+50°F = Evaporating temperature
range in °F
PS 34bar/
