Expansion Valve FRF is a thermostatic expansion valve, which is used in refrigeration systems to precisely control the flow of refrigerant into the evaporator. This control is achieved by sensing the superheat at the evaporator outlet with a temperature-sensing bulb, thereby ensuring that the refrigerant evaporates effectively in the evaporator and improving system efficiency. The following are some typical features and product descriptions of FRF expansion valves:
Precise Control: FRF valves can precisely control the flow of refrigerant to maintain the appropriate superheat in the evaporator.
External Balancing: With external balancing function, an external temperature-sensing bulb is used to sense the temperature at the evaporator outlet, providing more accurate flow control.
Applicable Refrigerants: Designed to be compatible with a variety of refrigerants, including but not limited to R134a, R410A, R22, etc.
Temperature Range: Suitable for a wide range of temperatures 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, ensuring durability in harsh environments.
Easy Installation: Designed for easy installation in existing refrigeration systems, 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.
