Abstract (en)
[origin: WO2016146742A1] A valve apparatus for mixing fluids comprising a plurality of digital valves. Each valve has an actuator for adjusting the pressure and/or rate of flow of fluid from a cylinder storing fluid, a mixer for mixing the flow of fluid from each valve to produce an output flow, a fluid analysis unit arranged to monitor the composition of the output flow, and a controller arranged to provide a target mixture concentration for the output flow. The controller transmits target data to the fluid analysis unit, the fluid analysis unit receives the target data, to determine any error in the monitored composition, and sends a correction signal to one or more of the valves for adjusting the flow. Each of the valves is able to receive a correction signal and to adjust the flow using the actuator.
