EV225B Servo-Operated 2/2-Way Solenoid Valve
Brand: DanfossEV225B is a servo-operated 2/2-way solenoid valve for use in steam applications.
The design is based on a PTFE diaphragm concept, ensuring highly reliable function when used in connection with contaminated steam.
Each valve body is made of dezincification resistant brass and the valve seats are made of stainless steel. This ensures a long life even in when used with highly aggressive steam.
