| Components | ||
| Style 5150 Live Loading Sets | 5150 live loading assemblies in conjunction with applied torque dramatically increase bolt travel due to deflection of the disc springs. The assemblies reduces valve leakage due to thermal cycling and packing wear. | |
| Style 1600 End Rings | Inconel wire-reinforced flexible graphite packing | |
| Style 5300 Sealing Rings | A square graphite precise density sealing ring with a low minimum gland load that creates a seal without large torque valves and friction. 5300 has a corrosion inhibitor to prevent stem pitting. | |
| Style 5100 Carbon Sleeve | 5100/5101 is a 99% carbon spacer that is used to retrofit deep stuffing boxes to reduce the number of rings to 5 in a valve. It is made to highly engineered tolerances and will not cause scoring of the valve stem. | |
