ABSTRACT:
A fluid control valve for use in severe erosive fluid conditions which includes a ceramic plug seat. The ceramic plug seat is mounted to a metal valve element using a tapered mechanical bolt. The tapered portion of the mechanical bolt matches a cone-shaped interior surface portion within the ceramic plug to uniformly distribute the mounting forces within the ceramic plug to prevent cracking of the ceramic plug.
