Balanced piston fluid valve, wherein annular outer and core inner coaxial valve members are adapted to move to and fro slidably relative to one another and to bar upstream-to-downstream fluid flow when mutually juxtaposed into seated position but adapted to enable such flow when spaced apart in unseated position.


Fluid valving method, comprising the steps of providing a valve body for laterally confining fluid flow to an open-ended substantially cylindrical passageway having a linear axis extending lengthwise between an upstream inlet opening and a downstream outlet opening, through which fluid is enabled to flow in open valving positions but is precluded from flowing in closed valving position; providing flow barriers disposed within said passageway and dividing the passageway cross-section into an inner flow-obtruding axial valve core portion whose maximum diam...
