The 8-inch ANSI Class 600 Masoneilan Camflex II Valve (METC SOA Test Valve No. A-15) accumulated 306 cycles in the Valve Static Test Unit (VSTU) and 901 cycles in the Valve Dynamic Test Unit (VDTU). METC SOA Test Valve No. A-15R accumulated 848 cycles in the VSTU and 5070 cycles in the VDTU. The test valve satisfactorily completed the ambient, 300/sup 0/F, and 600/sup 0/F static tests. The valve leakage rates exceeded the maximum allowable leakage rates during dynamic testing using limestone as the test medium. Excessive leakage occurred due to improper clearances between the valve parts and degradation of the valve sealant. The sealing surfaces showed minimal degradation as a result of exposure to solids. This - plus the design's similarity to other valves that have performed well in lockhopper testing - suggests that with appropriate modifications the Camflex II could have potential for use in solids-feeding lockhopper service.
