Abstract
A control valve comprising a valve housing including a valve cavity, an inlet means formed in the valve housing for directing fluid into the valve cavity, and an outlet means formed in the valve housing for directing fluid out of the valve cavity. The control valve further includes a valve element mounted for reciprocal movement in the valve cavity between open and closed positions and biased toward the closed position by fluid pressure forces. A valve seat is associated with the valve element which engages the valve seat when in the closed position and permits flow between the valve seat and the valve element when in the open position. A flow force inducing means is positioned adjacent the valve element for redirecting fluid from the inlet means through a predetermined flow path arranged relative to the valve element to cause fluid flow to impact the valve element and create flow induced forces of sufficient magnitude necessary to advantageously counteract the fluid pressure forces.
