Y Valve

A valve with one inlet and one outlet connection that provides unobstructed fluid flow. The flow is controlled by the action of a stem which lifts disk perpendicularly off center axis of its seat. The stem is at angle of less than 90 degrees (1.5708 radians) to parallel inlet and outlet flow. It may utilize a diaphragm as packing. Excludes valve, stop-check.
