Danfoss 068U4583 Thermostatic Expansion Valve R134a 3/8 x 1/2 ODF 3 Ton

The Danfoss 068U4583 is a thermostatic expansion valve designed to regulate the flow of liquid refrigerant into evaporators in air conditioning and refrigeration systems. This valve controls refrigerant injection based on superheat at the evaporator outlet, ensuring optimal system performance and protecting the compressor from liquid refrigerant damage.

Key Features:

• Designed for R134a refrigerant systems
• 3/8 inch inlet x 1/2 inch outlet ODF solder connections
• Rated capacity of 3 tons refrigeration
• Includes 3-foot capillary tube for remote bulb sensing
• Maintains constant superheat at varying load conditions
• Precision control for energy-efficient operation

This expansion valve is a critical component for maintaining proper refrigerant flow and system efficiency. The capillary tube allows flexible bulb placement at the evaporator outlet for accurate temperature sensing and responsive control.
