Specification Nominal capacity range Evaporating temperature range Maximum pressure PS 22. 4 to 54. 5 kW R22 see table on page 2 see table on page 2 Application Thermostatic expansion valves series TLEX are used in plants with one or more refrigerant circuits, in particular for series installations such as chiller units, heat pumps, and transport cooling. Maximum test pressure PF see table on page 2 (simultaneous on all connections) Max. bulb temperature Static superheat Length of capillary tube Bulb diameter brass stainless steel copper gas charge: 140 °C liquid charge: 70 °C approx. [. . . ] 5 K higher than the required evaporating temperature of the system. With gas charged valves and MOP it is under all operating conditions necessary that the bulb is always colder than the capillary tube and the thermal head!

An overbow is recommended in order to prevent the ingress of oil into the equaliser line. · The bulb should preferably be positioned on the upper half of a horizontal suction line but never after a liquid trap. As a general rule, bulbs of expansion valves should be insulated to prevent them being affected by the ambient temperature. · When soldering the valve, the valve body must not get warmer than 100 °C. · Do not bend or squeeze the bulb when thightening the bulb clamp! [. . . ] Increase of superheat setting results in a lower MOP value and vice versa.
