A.P. Services Graphite Pressure Seal Rings
A.P. Services Graphite Pressure Seals provide far superior sealing to metal pressure seal rings and result in easy valve disassembly. One of the most difficult areas of plant maintenance occurs with pressure seal design valves. Over the last five years there has been considerable research and development performed by A.P. Services Packing and several valve manufacturers to develop graphite pressure rings. Flexible graphite offers several advantages over pressure seals manufactured from silver plated soft annealed metal. |
