Seat Valve pneum. direct
Series A90-0815-Cryo
Valve A9023/0815/7555-HM-KP
2/2-way valve, externally pressure controlled in long shaft 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. The spring-loaded single-acting control actuator is sufficiently distanced from the cold source. The valve is controlled by a 3/2-way pilot valve. In addition, a pneumatic positioner for stroke control (input 4...20mA, 0...10V)) can be set up.
