The Nammo thermal vacuum facility used for EM testing is shown below. Upon successful completion of the CDR the Electronic Pressure Regulator is ready to undergo full qualification. Suitable for flow control of liquids and gases. The ARTES project took the Nammo Electronic Pressure Regulator system through from design concept to an all-welded, flight representative, extensively tested Engineering Model. Regulation accuracy of <0.05 bar (mechanical regulation is typically >0.2 bar).
The valves feature Nammos heritage hard sealing technology, making the whole system compatible with Xenon, Helium, Nitrogen, Hydrazine, and MON. System Schematic (shown with redundant branch). The Nammo High Pressure Proportional Valve.
The ISF is a Factory Mutual rated Nonincendive (Class II, Division 2 Groups C, D) electo-pneumatic closed-loop pressure control valve. ]]>, EUROPEAN SPACE AGENCY. Coping with a pressure range from 0 to 310bara, a flow range of <3 to 600mg/s Xenon & Helium and accommodating 3 different propellants (Xenon, Nitrogen and Helium) with a single proportionally regulating valve design. The QB2X implements external feedback and is often used to pilot dome loaded regulators like. Offered with standard 4-20 mA analog command signal. //-->
