  • Redundant valve system
    Patent number: 9803558
    Abstract: A redundant valve system to provide a regulated fluid flow includes a housing having an inlet at an inlet end which receives a pressurized fluid, and an outlet at an outlet end which provides the regulated fluid flow, a first piston assembly arranged in the housing having a first cavity, the first piston assembly configured to regulate the fluid flow, and a first fluid connection connected to the first cavity and to a point along the housing at the outlet end. The redundant valve system may further include a second piston assembly arranged in the housing downstream of the first piston assembly having a second cavity, the second cavity having a second fluid connection to a vent, an upstream valve to control the first fluid connection and control a position of the first piston assembly, and a downstream valve to control the second fluid connection and control a position of the second piston assembly.
