ABSTRACT:
A fluid valve includes a valve body having a fluid inlet and a fluid outlet. A valve seat formed from the valve body between the fluid inlet and fluid outlet for the passage of fluid therebetween. A movable valve member formed from ceramic material is positioned in the valve body between the valve seat and the fluid outlet for controlling the flow of fluid through the valve seat. The valve member is axially movable relative to the valve seat, with the quantity of fluid flowing through the seat to the fluid outlet being directly proportional to the distance between the valve member and the valve seat.
