Danfoss 068Z3403 Thermostic Expansion Valve
Danfoss 068Z3403 Thermostic Expansion Valve
Product Description :
- It is a crucial component in refrigeration and air conditioning systems. Its primary function is to regulate the flow of refrigerant into the evaporator coil based on the cooling load requirements.
- It controls the amount of liquid refrigerant flowing into the evaporator coil, maintaining the desired superheat (temperature of refrigerant vapor) at the evaporator outlet.
- It has a sensing bulb connected to the evaporator outlet or suction line. This bulb contains a temperature-sensitive charge (typically a refrigerant or other substance) that expands or contracts based on the temperature of the refrigerant leaving the evaporator.
-
A Thermostatic Expansion Valve (TXV) is a precision control device used in refrigeration and air conditioning systems to regulate the flow of refrigerant into the evaporator coil. It automatically adjusts the refrigerant flow rate based on evaporator temperature and pressure, ensuring optimal cooling performance and energy efficiency.
-
Built with durable brass or stainless steel components and designed for accurate thermal response, the TXV maintains a consistent superheat level to prevent liquid refrigerant from entering the compressor, thereby protecting the system and enhancing reliability.
