Turn adjusting stem clockwise to increase

Thermostatic expansion valves, also known as TXVs or TEVs, are metering devices that maintain superheat. They contain an external equalizer. External equalizers give the pressure reading that you would normally take with a suction gauge at the end of the evaporator coil. They supply the closing force to the TXV. TXVs also contain a sensing bulb.

Dec 15, 2017 · The ballast dampens the rate of expansion within the bulb, stabilizing the bulb pressure against the diaphragm by dampening the rate of temperature change to the bulb charge compared to the rate of temperature change of the suction line. This stabilization ensures that the TXV operates more efficiently and better protects the compressor.

There is also a spring that may have an adjustable tension that provides additional closing force. When working properly, these forces achieve a balance and maintain the evaporator superheat to the designed set levels at the end of the evaporator. The TXV's job is to maintain superheat within certain …Fan cycling is the easiest and cheapest way to maintain a minimum head pressure.
