Product Details

The thermostatic expansion valve (TXV) is a critical refrigeration component that modulates refrigerant flow into the evaporator coil based on superheat conditions. By maintaining the correct superheat level, the TXV protects the compressor from liquid slugging while maximizing heat transfer efficiency. The 30″ capillary tube provides flexible bulb placement for accurate sensing across a variety of installation configurations.

Application

• Designed for use in York residential and light-commercial split-system air conditioners and heat pumps
• Suitable for R410A refrigerant systems rated at 1 ton nominal capacity
• Ideal for service, repair, and OEM replacement applications

Why Choose an OEM York TXV?

Using a genuine York replacement TXV ensures compatibility with your existing system controls, coil design, and refrigerant charge. An improperly matched TXV can result in poor efficiency, compressor damage, or comfort complaints — making the correct OEM part the smart choice for any HVAC professional.
