Valve A9128/0804/5242-A9 AC

2/2-way solenoid valve made of stainless steel in long spindle design for liquefied gases (LN2 nitrogen, LCO2 carbon dioxide) down to -196°C. The spindle extension allows the valve body to be very well insulated. Since the solenoid actuator is sufficiently distant from the cold source, the heat input can be considered negligible. Furthermore, this valve design can be used with EEx solenoids for Ex protection zone I.
