Graphite Die formed Ring
CODE:BOTE-GDR
Description:
BOTE-GDR Graphite Die formed Ring is die-pressed by low sulfur expanded graphite, with precise size and undefined density, and without any extra filler or adhesive. The purity of the graphite is more than 98%, does not need any anti-corrosion treatment. Generally, the section of the filler ring is square, also can be wedge-shaped or v-shaped, the later two shapes are suitable for high pressure position.
Reinforced graphite formed ring
it is die-pressed by pure flexible graphite, and inner lined with metal, the reinforced material can be stainless steel foil, mesh or other materials.
APPLICATION:
It has all properties of expanded graphite, can bear violent alteration of temperature and pressure. It is ideal packing for valves and static seal in almost all applications. Can be used as stand-alone packing or in combination high carbon fiber anti-extrusion packing rings, except when stems are severely damaged.
BOTE have cooperation with more famous Valve manufacturer in the world.
