DEFINITION

Classification: 137/861

With flow control means for branched passages:

(under subclass 561) System wherein an array of branched fluent material flow passages is provided with means to stop or regulate the flow in more than one branch, which means may comprise (1) multiple valves, (2) a deflector or valve located at a junction and operable to open one passage and close or restrict the flow from the other, or (3) a single valve controlling one outlet flow path, the hydrostatic characteristics of the system being such that the entire flow passes through the valved line when it is fully open.

(1) Note. See the class definition, Lines With Other Classes (2) Plural Valves, and Subclass References to the Current Class 4 for search notes of plural valves and their actuators.
