VP70 is a square-braided from high quality carbon yarns impregnated with pure graphite, special high temperature lubricants and Molybderum Disulphide. The carbon yarns are dense braided to provide a near frictionless, self-lubricating seal. Graphite power provides non-migrating lubricant between the packing and the shaft. The non-glazing, high temperature lubricant protects during the packing break-in period. The addition of Molybderum Disulphide. gives high temperature and high pressure lubrication with shaft wear protection even when contact pressures between packing and shaft are excessive.
Used for pumps or valves in high pressure and high temperature. Handle water, steam, acids and alkalis for power stations, refineries, boiler plants etc.
VP70 is commonly used in stem turbines, high temperature motor-actuated valves and for high pressure, high temperature valve application in general.
