Valve with shuttle for use in flow management systems

A valve for use in a flow management system comprising:

• a valve body with a spill port between valve ends;
• a shuttle located in a chamber of the valve body;
• the shuttle having a through hole extending linearly between a shuttle closure end and a shuttle spring end;
• a first seat located in the through hole and a first seat closure which closes against the first seat when the first seat closure moves toward the shuttle spring end;
• a second seat located above the spill port at the interior of the valve body;
• a second seat closure located on the shuttle closure end;
• a spring located to one side of the spill port;
• the spring between the shuttle spring end and a valve inlet;
• the valve operable to pass a flow entering the through hole at the shuttle spring end and to spill a flow that closes the first seat closure;
• the spring urges the shuttle to block the spill port;
• a shuttle perimeter for sealing against a valve body interior and for forming a movable seal;
• and,
• a cage limiting the motion of the first seat closure, the cage including a stabilizer preventing the first seat closure from blocking flow entering the through hole at the shuttle spring end.
