Vulcan Types VR3 are braided packing, constructed from 100% Grafan yarns, to form truly exceptional capabilities and performance, pure Expanded Graphite packing.
Under compression in the gland, Types VR3 die-form into packing rings like VR2, whilst offering the advantage of avoiding the need to laboriously wrap VR1 ribbon tape around valve stems or the cost of an inventory of many sizes of individual VR2 die-formed rings.
Types VR3 can be merely cut to length and spiralled into the gland. There is no need for individual cut rings, as is the case with conventional braided packing. Grafan is self-lubricating and will not shrink nor harden nor dry out in use. Type VR3 standard spool length is 8 metres.
Applications: Extreme condition, long life and zero leakage packing for all uses, up to high temperature, high-pressure, high-speed applications on pumps, valves, mixers, agitators, expansion joints, ball valve seats and other static seals. Types VR1 are designed for use in static applications only. Against all acids, alkalis and solvents (except very strong oxidants), gases, feed water and superheated, or saturated steam.
