Abstract
The present invention comprises an improved ceramic gate valve having within the valve housing a ceramic valve gate, which is surrounded by a peripherally disposed compression band for providing strength thereto, and which is engaged by a pair of ceramic valve seats, which are in turn urged inwardly for such engagement by ceramic springs. The ceramic springs comprise a plurality of plates of ceramic material separated by spacers which are disposed in a staggered array to form the ceramic spring.
