The Everlasting Sliding-Disc Valve (METC SOA Test Valve No. B-3) accumulated 740 valve cycles in the Valve Static Test Unit and over 16,000 valve cycles in the Valve Dynamic Test Unit. Only minor operating problems, primarily erratic motion and some scoring of the seating surface, where encountered with coarse limestone (5/16''x 1/8'') particles. Operation with fine solids (100-mesh limestone) showed excellent performance. The actuator level arm failed twice but a change in clearances solved the problem. Based on its performance in testing, the Everlastinc Sliding-Disc Valve, with minor modifications, is a very promising choice for feedside lockhopper service in coal conversion and utilization.
