Seat Valve electrically force-controlled
Series B9123-B9128/1315 CRYO
Valve B9128/1315/4272-DH DC
2/2-way stainless steel solenoid valve in cryogenic design for liquefied gases -196°C (LN2 nitrogen, LCO2 carbon dioxide). Due to the spindle extension, the valve body can be very well insulated or installed in a vacuum insulated coolbox. Since the solenoid is sufficiently removed from the cold source, the heat input is considered to be negligible. In addition, this valve design can be used with EEx magnets for explosion protection Zone I.
