032F6225 Danfoss EVRA 25 Solenoid Valve 0-35Bar DN25

1.Overview of the 032F6225 Danfoss EVRA 25

The Danfoss 032F6225 corresponds to the EVRA 25. This solenoid valve, part of the Danfoss EVRA series, is a normally closed, flange-mounted solenoid valve primarily used in industrial refrigeration systems. Featuring a cast iron body, this solenoid valve is suitable for a variety of common refrigerants, including ammonia (R717). It operates stably under demanding operating conditions, providing on-off control of refrigerant pipelines.

The Danfoss 032F6225, a 25 mm flange-mounted, zero-pressure differential-opening servo solenoid valve, offers a cooling capacity of 10 m³/h per pass, completes defrost operations from -40°C to 130°C, and boasts a lifespan of millions of cycles, making shutdown of large ammonia/fluorine systems safer and more energy-efficient.

Servo-Diaphragm Actuation: The EVRA series solenoid valves utilize a servo-diaphragm actuation design, which enables fast valve response and allows actuation with zero or very low differential pressures, which is particularly beneficial during system startup or under specific operating conditions.

Flexible Component Ordering: Like other EVRA series models, the EVRA 25 solenoid valve can be ordered as a complete assembly or individually, including the valve body, coil, and flange. This facilitates spare parts inventory management and maintenance replacements.

Suitable for Harsh Service Applications: The solenoid valve's wide media temperature range and cast iron body make it suitable for the challenges commonly encountered in industrial refrigeration environments.
