摘要： A slide valve for use in a high temperature gas line is described. The valve is constructed to allow field assembly and disassembly for ease of service, and has insulating means and gas purge means for maintaining the exterior of the valve housing at a low temperature. The valve includes a slide plate which can be provided with a flow opening in either a first location such that the slide plate is in tension when the valve is closed while hot or in a second location such that the slide plate is in tension when the valve is opened while hot.
