Carrier 340620-719 Thermal Expansion Valve (TXV)

The Carrier 340620-719 is an OEM Thermal Expansion Valve (TXV) engineered for use in Carrier refrigeration and air conditioning systems. Thermal expansion valves are critical metering devices that regulate the flow of refrigerant into the evaporator coil, ensuring optimal system performance, energy efficiency, and reliable temperature control under varying load conditions.

Key Features

• OEM Carrier replacement part — engineered to exact factory specifications
• Precisely meters refrigerant flow into the evaporator for optimal heat transfer
• Maintains consistent superheat control across varying system loads
• Helps protect the compressor from liquid refrigerant slugging
• Direct drop-in replacement for compatible Carrier equipment
• Supports reliable, long-term system operation and efficiency

Why Thermal Expansion Valves Matter

The thermal expansion valve is one of the most important components in a refrigeration or air conditioning system. By modulating refrigerant flow in response to evaporator outlet temperature and pressure, the TXV ensures the system operates at peak efficiency while safeguarding the compressor from damage. Replacing a faulty or worn TXV with a genuine Carrier OEM part like the 340620-719 restores proper system balance and helps avoid costly compressor failures.

Application

• Designed for use in compatible Carrier air conditioning and refrigeration systems
• Ideal for HVAC technicians performing routine maintenance or system repairs
• Recommended for use with the refrigerant type specified in the original Carrier equipment documentation

Important Note

Always consult the original Carrier equipment documentation or service manual to confirm compatibility before installation. Use of the correct refrigerant type and proper installation practices are essential for safe and efficient operation.
