DANFOSS EV22OB - 2/2-Way Normally Open Servo-Operated Solenoid Valve
The DANFOSS EV220B series encompasses 2/2-way servo-operated solenoid valves engineered for robust and reliable flow control in demanding industrial environments. Designed for high-temperature and high-pressure media such as steam, hot water, and neutral fluids, these valves utilize an external solenoid coil for precise electrical actuation. Their normally open (NO) configuration ensures fail-safe flow in the absence of power, making them suitable for critical process control, heating, and cooling applications.
