The TU stainless steel thermostatic expansion valves allow you to control the refrigerant flow to the evaporator. The valve senses the refrigerant level and, when needed, injects liquid to keep the air conditioning system working at an optimum level.
The TU valves are compact in design, light weight and have steel/copper bi-metal connections for fast soldering. The TU valves offer fixed or exchangeable orifices and adjustable or non-adjustable superheat settings, as well as internally or externally equalized designs. The TU valves are available in angle- or straight way designs and with many combinations of solder connections.
The TU valves ensure consistent function throughout the service life. The valves come with high dirt-retention filter and the TUA(E) versions with exchangeable filter, offer easy maintenance (or e.g.: cleaning of filter). For safe and reliable operation, the TU valves can be supplied with self-cleaning bleed or with a MOP charge.
