The valve manufacturer’s instructions give the number of stem turns per degree of superheat. The HVAC TXV, which stands for Thermal Expansion Valve, is a precision-machined refrigeration component used in HVAC systems to control the amount of refrigerant that flows through the evaporator coil. The TXV is constantly making fine-tuned adjustments to control the temperature of your air conditioner coil.The Sporlan Type ER balanced port thermostatic expansion valve has a brass bar stock body. The ER valve has ODF connections in a variety of commons sizes, and has an optional inlet strainer available. There is also an option for a 15% bleed port, if required.

Check the SH at the evaporator outlet. If SH is between 5°F - 12°F, the TXV is controlling properly. If SH is less that 5°F, the SH adjustment may be too low. Adjust the SH by turning the adjustment stem clock-wise to increase the SH. Wait 20 minutes for the system to balance and ad-just again as required.So, adjusting the TXV is NOT the way to deal with low suction pressure. You only adjust a TXV to make it reach the target superheat. Also, see if you’re measuring superheat inside or outside; the outside superheat may give you an inaccurate reading due to the likelihood of higher ambient temperatures. Not all expansion valves are adjustable.

By:Bryan Orr The piston (fixed orifice) and TXV (thermostatic expansion valve) are the two most common metering devices in use today, though some modern systems utilize an electronically-controlled metering device called an EEV (electronic expansion valve). It should be noted that there are other types of fixed-orifice metering devices, like capillary …Aug 4, 2022 · On an adjustable valve, increasing the spring tension/force results in lower flow and higher superheat, and decreasing the spring tension/force results in more flow and lower superheat.
