# Brittle material valves

## Abstract

Some aspects of the disclosure provide a valve system that includes a valve made of brittle material, such as ceramic, graphite and the like. In some examples, the valve is made of one or more materials that remain a solid state in a temperature range of 1000° C. to 3000° C. The valve includes a valve housing with a cavity extending in a length direction of the valve. The valve housing includes a first port aligned with the cavity and a second port that is formed on a side of the cavity. The valve includes a plunger that is movable in the cavity of the valve housing and configured to control a fluid flow between the first port and the second port. Methods of forming the valve and operating the valve are also provided.
