The thermostatic expansion valve (TEV or TXV) is erroneously considered by some to be a mysterious and complex device. As a result, many valves are needlessly replaced when the cause of the system ...

The thermostatic expansion valve (TXV or TEV) is a metering device located between the refrigeration system’s liquid line and the evaporator. It is a rather complex valve with a remote bulb feedback ...

Expansion Valves are widely used in refrigeration and air conditioning systems to modulate the flow of refrigerants. This facilitates precise control of superheating and promotes compressor ...

Also, if you are installing PEX systems with ASTM F1960 expansion connections, ASTM F1960 includes a list of recognized forged brass alloys. It is important that you use valves manufactured using one ...

and controls the freon flow through the system (and the pressure difference between the two sides). The inlet side of the valve is at high pressure and the freon is a room temperature liquid at this ...
