Abstract
A high-pressure fluid control valve is disclosed for operating a fluid-actuated device. Preferably a ball-poppet and frusto-conical valve seat adapted for substantially line-type contact therebetween are provided with an upstream restricted flow area in order to substantially minimize sonic flow damage to the actual sealing surface of the valve seat. Preferably, the ball-poppet is movable within a poppet guide that is allowed to float radially in order to allow the ball-poppet to be substantially self-centering with respect to the valve seat. In addition, cross-over leakage is preferably negated by closing an exhaust ball-poppet just prior to opening a supply ball-poppet.
