Abstract

HIGH PRESSURE VALVE A valve comprises a one piece valve body defining a fluid passage in which a closure member is disposed for selectively allowing and blocking fluid flow therethrough. A top entry stem extends into the valve body to transmit motion to the closure member. An integral external retainer is provided for cooperating with an outer abutment surface of the stem to prevent the same from being blown out of the valve body during use. A thrust bearing is disposed between the abutment surface of the stem and the external retained to reduce the operating torque. The one piece valve body design eliminates the joints and seals which are potential leak paths and the external retainer ensures that the thrust bearing be not influence b1r the temperature of the processed fluid.
