Danfoss Thermostatic Expansion Valve

The Danfoss thermostatic expansion valve (TXV, also called a TEV or thermal expansion valve) meters liquid refrigerant into the evaporator of an air conditioning or refrigeration system. It responds to changes in evaporator superheat, so refrigerant flow follows the cooling load.

Key Features:

• Thermostatic design adjusts refrigerant flow automatically to match system demand
• Helps keep evaporator superheat stable, which supports efficient operation
• Helps protect the compressor by limiting liquid refrigerant return
• Brazed ODF (sweat) connections for a leak-resistant installation
• Built by Danfoss, a long-established manufacturer of refrigeration and HVAC controls

These valves suit commercial and residential A/C and heat pump applications. They are offered in several capacities and connection configurations, and some variants are intended for R410A systems. Choose the variant whose capacity, refrigerant and connection sizes match your system.
