Expansion Valve QRF is a thermal expansion valve that is primarily used in refrigeration systems to control and regulate the flow of refrigerant into the evaporator. This valve is essential to maintaining system efficiency and performance. Here are some typical features and product descriptions of QRF expansion valves:
Precise flow control: The QRF valve is able to precisely control the flow of refrigerant, ensuring 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 of the evaporator outlet, thereby more accurately controlling the refrigerant flow.
Applicable refrigerants: Designed to be compatible with a variety of refrigerants, such as R134a, R410A, R22, etc.
Temperature range: Applicable to 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 accommodate 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 with maintenance convenience in mind, facilitating regular inspections and necessary adjustments.
Model Diversity: A variety of models and specifications are available to accommodate different flow requirements and system configurations.
Technical Data: Provides detailed technical data, 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.
