Graphite packing sleeves
We deliver graphite packing sleevs that are an essential parts of any valve. Fitting around to spindle to ensure its smooth action and prevent leakage The effective sealing properties, combined with the ease with which it can be removed and replace ensure graphite is the material of choice.
We can supply sealing sleeves which are compatible with all major brands of manufacturers of valves, for example.: Klinger, Gresswell, Shaw, Bont, Level RCM, Dewrance, Hopkinsons and many others.
Graphite Sleeve Packing
Packing sleeves are used in many brands of gauge cock, to prevent leakage and to ensure effective operation. They are made from 99.5% pure graphite, with stainless steel eyelets, the computer controlled compression, ensure a standard, quality product.
A popular application of graphite sleeve is to seal the drain cocks for level gauges (see. fig. below). The use of graphite sleeves provides smooth and reliable operation of the cocks and high resistance to erosive action of the medium and pollution.
The size of sleeve must be exactly matched to the size of the valve (cock). We supply sleeves of standard size as shown in the table:
1) Dewrance 1/2" (cone)
2) Dewrance 3/4" (cone)
3) Shaw Son and Greenhalgh 20 mm
|In some applications it is possible to use sleeves which, instead of graphite are made of Aramid/PTFE. This solution is usually cheaper, but may be used at lower temperatures (up to 250 °C) than the graphite sleeves (p to 550 °C). The sleeves of the aramid / PTFE are harder and more fragile than their graphite counterparts.|
Graphite sealing rings
We supply graphite sealing rings with standard dimensions shown in the table below.
