A flow control valve for instant on-off operations with gases or liquids at relatively high pressures, such as pressures between 10,000 psi and 100,000 psi. The valve includes a valve body having two or more valve cavities in communication with each other and defined by two end seal assemblies and one or more valve port seal assemblies. An elongated, round, sliding valve stem is centrally located through the seal assemblies. End plugs are used to support the end seal assemblies. The valve stem has fluid passages which are preferably machined at a mid-section of the valve stem. The valve stem is slid parallel to its longitudinal axis to allow or prevent communication between the valve cavities by way of the fluid passage of the valve stem. Two opposite ends of the valve stem are either not exposed to the working fluid or are exposed to different pressures of the working fluid. With both opposite ends of the valve stem not being exposed to the working fluid, fluid-induced forces of relatively high magnitude are not exerted on the valve stem.

Abstract

A flow control valve for instant on-off operations with gases or liquids at relatively high pressures, such as pressures between 10,000 psi and 100,000 psi. The valve includes a valve body having two or more valve cavities in communication with each other and defined by two end seal assemblies and one or more valve port seal assemblies. An elongated, round, sliding valve stem is centrally located through the seal assemblies. End plugs are used to support the end seal assemblies. The valve stem has fluid passages which are preferably machined at a mid-section of the valve stem. The valve stem is slid parallel to its longitudinal axis to allow or prevent communication between the valve cavities by way of the fluid passage of the valve stem. Two opposite ends of the valve stem are either not exposed to the working fluid or are exposed to different pressures of the working fluid. With both opposite ends of the valve stem not being exposed to the working fluid, fluid-induced forces of relatively high magnitude are not exerted on the valve stem.
