Expansion Valve ERF is a thermostatic expansion valve mainly used in refrigeration systems to control and regulate the refrigerant flow into the evaporator. This valve is essential to maintain system efficiency and performance.
Here are some typical features and product descriptions of Expansion Valve ERF:
Precise flow control: ERF valves can accurately control the flow of refrigerant to ensure complete evaporation of refrigerant in the evaporator, thereby improving refrigeration efficiency.
External balancing: With external balancing function, an external temperature sensing package is used to sense the temperature at the evaporator outlet, so as to more accurately control the refrigerant flow.
Applicable refrigerants: Designed to be compatible with a variety of refrigerants, such as R134a, R410A, R22, etc.
Temperature range: Suitable for a wide range of temperatures, able to meet the needs of different refrigeration and air conditioning systems.
Maximum operating pressure (MOP): With a high maximum operating pressure to adapt to high pressure conditions in the system.
Material: Usually made of corrosion-resistant materials such as stainless steel or brass to ensure durability in harsh environments.
Easy installation: Designed for easy installation in existing refrigeration systems, usually including necessary connections and installation instructions.
Easy maintenance: Designed for easy maintenance, regular inspection and necessary adjustments.
Model diversity: A variety of models and specifications are available to accommodate different flow requirements and system configurations.
Technical data: Detailed technical data is provided, including rated capacity, temperature range, connection size and pressure rating.
Wide application: Widely used in commercial refrigeration, industrial refrigeration, transport refrigeration and air conditioning systems.
Compliance: May comply with specific industry standards and specifications, such as ASHRAE, ISO, etc.
