THERMOSTATIC EXPANSION VALVE FUNCTION. The function of a TXV is to regulate the flow of refrigerant into the evaporator coils depending on the superheat required. The TXV consists ofa sensory bulb filled with gas that senses the evaporator pressure. A spring beneath the diaphragm of the valve also exerts pressure.

You can use the OEM valve for the evaporator coil if it is available or you can use a Parker Universal A/C or heat pump TXV. Select the valve you need: 1½ - 3 ton R22. 3 - 5 ton R22. 1½ - 3 ton R410A. 3 - 5 ton R410A. Select the correct adaptor to fit the existing coils connection: Aeroquip, Chatleff or mail flare.An H-block expansion valve also has a dome, but the gas filled tube is inside the H-block valve. H-block expansion valves are often mounted on the firewall inside the engine compartment, although the can also be mounted inside on the evaporator coil. A block style expansion valve uses a temperature sensing disc rather than a remote sensing bulb.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. With the recommended superheat value from the manual in hand, proceed to make the adjustments on the TXV. Locate the adjustment stem on the TXV; it’s a small protruding screw-like part usually found on the bottom or side of the valve. Use an adjustable wrench to turn the stem; a clockwise turn will increase the superheat while a ...

The valve can be delivered with or without internal check valve and with an external superheat adjustment spindle for field retrofit. The TR 6 valve has a balanced port design to reduce the influence from varying condensing pressures.

In the automatic expansion valve, the spring pressure along with the atmospheric pressure acts on the diaphragm and pushes it down. As a result, the needle also tends to move down away from the seat leading to the opening of the valve. The evaporator pressure pushes the diaphragm in an upward direction. Due to this, the needle tends to move in ...
