Abstract
A reduced wear single input valve includes a valve stem that has a first end and a distal end, and a valve housing that has an input port and an output port. The valve stem pass through a seal interfaced to valve housing at the output port side. A valve seat is within the valve housing has one side in fluid communication with the output port and an opposing side in fluid communication with the input port. A ball is urged against the valve seat by a force of a resilient member, thereby preventing flow of fluid from the input port through the valve seat and to the output port until an opposing force is applied on the ball by the valve stem, thereby counteracting the force of the resilient member. The valve stem is isolated from a pressure from the input port while the ball is seated.
