Abstract
An electronic pressure regulation system includes an electronic control unit and a fluid assembly, with the fluid assembly including a fluid control branch having a proportional control valve and a heater. The heater may be a strip heater applied to or a coil wrapped around an external surface of the proportional control valve. The system may further include a latching isolation valve. A secondary fluid control branch can be included, and the fluid control branches can be in parallel. The electronic pressure regulation system can be included in an all-electric satellite. Another electronic pressure regulation system includes an electronic control unit and a fluid assembly, with the fluid assembly including a fluid control branch having a proportional control valve, the proportional control valve including two independently-controlled coils for magnetostrictive actuation.
