Abstract
Valves are provided for controlling flow along a fluid line that includes an outer shell and an inner housing slidably disposed therein that includes connector threads surrounding a boss on one end and a passage including a tapered region within the boss. A shaft within the valve includes a base coupled to the outer shell, a tapered sealing pin disposed within the tapered region, and a fluid passage extending through the base to outlets in the sealing pin. A connector may be threaded into the one end of the inner housing, thereby slidably engaging the connector threads, camming elements on the inner housing causing the inner housing to move helically from a closed position wherein the sealing pin engages the boss to seal the outlets and an open position wherein the inner housing is directed away from the sealing pin to open a fluid path through the valve.
