Seat Valve pneum. direct
Series A9021-A9023/1015 CRYO
Valve A9023/1015/7058-NG-4R
2/2-way valve, externally pressure-controlled in cryogenic design for liquefied gases (LN2 nitrogen, LCO2 carbon dioxide) down to -200°C. Due to the spindle extension, the valve body can be isolated very well. The spring-loaded single-actuator is sufficiently removed from the cold source. The valve is controlled via a 3/2-way pilot valve. In addition, a pneumatic positioner for the stroke control (input 4 ... 20mA, 0 ... 10V)) can be set up.
