Anchor/Darling Double-Disc Gate Valve, METC SOA Test Valve No. A-12 and Test Valve No. A-12R state-of-the-art Lockhopper Valve-Testing and Development Project. Summary test report

Technical Report ·
OSTI ID:6349923
The Anchor/Darling Double-Disc Gate Valve (METC SOA Test Valve Nos. A-12 and A-12R) performed well in testing with clean gases. The packing developed some leakage, but it could be controlled by tightening the packing gland. In both dynamic and slurry testing, solids accumulated in the bonnet and internals, jamming the valve. The forces on internal parts as a result of the jamming were sufficient to crack the hardfacing on the seats and discs. Any design with voids that can be packed with particles will have difficulty handling solids media. It is recommended that no further testing be performed on this valve.
