What is EVR type solenoid valve?

EVR type solenoid valve is a type of solenoid valve produced by Danfoss for refrigeration systems, mainly used to control fluid flow in liquid, suction, and hot gas pipelines. Its core features include:
Applicable scenarios
Suitable for fluorinated refrigerants (such as R22, R134a, etc.) and natural refrigerants (such as R290, R600a), suitable for refrigeration, refrigeration, and air conditioning systems.  ‌
Structure and function
Design: Adopting direct or pilot operated design, supporting unidirectional flow control.  ‌
Sealing performance: The valve seat and sealing area are designed with precision to ensure fluid control accuracy.  ‌
Split supply: Valve bodies, coils, and other components can be ordered separately for easy maintenance and replacement.  ‌
performance parameters
Medium temperature: up to 105 ℃, some models support 130 ℃.  ‌
Maximum pressure difference: The maximum working pressure difference of liquid pipelines can reach 38 bar, while that of gaseous media is about 1 bar higher.  ‌
Flow range: Kv value (flow coefficient) ranges from 0.16 to 5.0, depending on the model and medium.  ‌
Typical Applications
Commonly used in industrial refrigeration, HVAC, and marine equipment, such as controlling the direction of refrigerant flow or regulating flow rate.  ‌
