EV250B Assisted Lift Operated 2/2-Way Solenoid Valve

Brand: Danfoss

EV250B with assisted lift can operate from zero and up to 10 bar differential pressure. 

This 2/2-way valve program is especially to use in closed circuits with low differential pressure, but demanding moderate flow rates. 

Valve body in dezincification resistant brass for ensuring a long life even in connection with aggressive steam media. 

EV250B is compatible with the broad Danfoss coil program with enclosures from IP 00 up to IP 67. Medium temperatures up to 140° C (low pressure steam).
