ABSTRACT:
A valve apparatus having a three-flow line connectable flow housing with the valve closure located to enable control of the flow through the branch line while leaving primary straight through flow unaffected. The branch line flow is controlled by a conventional vertically reciprocable gate-type closure operated by a rotatable stem. The valve apparatus combines the functions of a conventional Tee-fitting and block valve in a relatively inexpensive unit. The disclosed valve apparatus is particularly useful in fluid flow networks or systems in which a primary conduit is provided with branch connections.
