FLUID CONTROL VALVE DEVICE

摘要

Certain embodiments of a fluid control valve 100 include one or more ceramic components that operate substantially free of tensile stress concentrations along the control surfaces. In some embodiments, a fluid control valve 100 includes a ceramic plug 140 having a set of longitudinal grooves 142 milled in the cylindrical surface 141 of the plug to define control surfaces 143. The plug is disposed in an internal longitudinal cavity 120 of the valve body 110 such that the fluid flows over the plug's control surfaces in a direction substantially parallel to the control surfaces. The ceramic plug and other ceramic components may be manufactured using relatively simple machining techniques to reduce the overall production costs.
