The Asco 8015B221 Solenoid Valve is engineered for high-temperature steam applications requiring strict control over activation and restart conditions. Its latching design ensures the valve remains shut under power loss and must be intentionally reset after each trip, making it ideal for installations where safety and manual validation are critical.
