Linear actuated 3 way spool valve with constant total flow

A valving system having a plurality of linear actuated valves, comprising:

• a manifold comprising a plurality of hollow interior portions, wherein a portion of the manifold surrounds each hollow interior portion, and is referred to as an internal valve housing, and wherein each internal valve housing comprises a housing inlet, a first housing outlet and a second housing outlet, each in communication with the hollow interior portion;
• and wherein each valve comprises:
• the internal valve housing;
• a spool disposed in the hollow interior portion and having a first passageway and a second passageway, where a first end of each passageway converge at an inlet opening, forming a first portion and a second portion of the inlet opening, a second end of the first passageway comprises a first outlet opening and the second end of a second passageway comprises a second outlet opening;
• and
• an actuator to translate the spool along a major axis of the spool;
• wherein the housing inlet of each valve is in communication with an inlet port, the first housing outlet of each valve comprises a dedicated output and communication with a common outlet port.
