V120 deformed rings are produced by compressing an exact amount of grafan ribbon tape in precision metal moulds. The result: uniform quality, dense, smooth finished, close tolerance, die-formed rings. A large range of grafan rings are available ex-stock. Any custom size or shape can be produced usually from existing tooling with a range of densities available from 1 to 1.8gm/cc. V120 die-formed rings are supplied to size for ease of fitting. When energized in the gland, the rings compress to effect a perfectleack-free seals on valves. It is well proven that valves packed with this material have been in service for years, without leakages or maintenance, where previous braided packing have failed in weeks or months.
Extreme condition, long life and zero leakage packing for all purposes under high temperature, high pressure, high speed applications on pump, valves mixers, agitators, expansion joints, ball valve seats and other static seals. V120 are designed for use in static applications only. Resistant against all acids, alkalis and solvents ( except very strong, oxidizers), gases, feed water and super heated or saturated steam.
