Abstract
A fluid control system 10 and selector valve 24 for use therein, for controlling a plurality of fluid actuated elements 12, such as valve operators. The fluid actuated elements are controlled from an operating station 52, which is located remotely from the fluid actuated elements 12. Instructions regarding which of the fluid actuated elements 12 it is desired to operate are transmitted by coded signal from the operating station 52 to the selector valve 24, which is positioned proximate the fluid actuated elements 12. The coded signal is transmitted in binary form through a plurality of code input lines 30, each code input line carrying one binary digit of the code. Each of the fluid actuated elements 12 is represented by a corresponding binary code. In response to receiving the binary code corresponding to a given one of the fluid actuated elements 12, the selector valve 24 establishes a fluid circuit serving to introduce fluid pressure to or release pressure from that one of the fluid actuated elements 12, causing it to alter its condition. The present invention is especially well suited for use in the hydraulic control of a satellite well subsea production system.
