Combined valve modular control panel
First Claim
1. A modular control valve panel, comprising a plurality of at least two separable valve modules arranged end-to-end, each said valve module having a valve chamber therein, a supply module at one end of said plurality of valve modules, a bleed module at the other end of said plurality of valve modules, a supply passage having an inlet in said supply module and leading from said supply module through said valve modules into said bleed module, a bleed passage extending through said plurality of valve modules into said bleed module, each valve module having valve means operable in a first mode to open its valve chamber to said supply passage while sealing it from said bleed passage, in a second mode to open its valve chamber to said bleed passage while sealing it from said supply passage, and in a third mode to seal its valve chamber from both said supply passage and said bleed passage, means for supplying fluid under pressure to said inlet of said supply passage, a bleed outlet in said bleed module, and valve means in said bleed module operable selectively to place said bleed outlet in communication with said supply passage while sealing it from said bleed passage, to place said bleed outlet in communication with said bleed passage while sealing it from said supply passage, and to isolate said bleed outlet from both said supply passage and said bleed passage.

Abstract
A valve modular control panel having a gas supply module at one end of a row of valve modules and a bleed module at the other end. Each valve module is individually controlled by its own valve mechanism. Gas under pressure is suppled to all of the valve modules from an inlet in the supply module by a passage running through all of the valve modules and terminating in the bleed module. A bleed passage runs through the valve modules and into the bleed module. All valve modules are bled through the bleed module. The bleed module is also capable of exhausting the supply passage. The panel can be expanded or contracted to include any number of valve modules which are releasably secured together by a series of nuts and tie rods. A protective shield for the panel can be adjusted in size depending on the number of modules in the panel.
