Graphited PTFE Packing |
Braided from graphited PTFE (gPTFE) plain yarn. The packing is soft, with low density There are no free particles of graphite on surface and therefore no contamination can occur.
For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings. Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents. It is also against water, steam, petroleum derivatives, vegetable oil and solvents. |

PTFE Filament Packing |
| Made of sintered, highly stretched PTFE multifilament yarns with thoroughly PTFE impregnation. The packing is then re-impregnated with a mix of PTFE emulsion during braiding operation. Good resistance to compression and to extrusion, high structural and cross-sectional density.
High red elastic rubber core can absorb vibration, to control leakage.
Especially suited for high pressure valves, plunger pumps, agitators, mixers etc. and where contamination is not permitted.

PTFE valve stem filling
|
|
PTFE Valve stem filling is a soft product which by material of PTFE resin, it is white color, continue rope shape and the cut surface is circle. It has high gentle peculiarity, excellent filling peculiarity, lubrication self peculiarity, low rub factor and resistant corrode and so on.
|
|
|
Main Specification: |
Advantage: It is easy to fill in and you not need to dismantle the valve, only just reel the rope shape packing on valve lever and push, then screw down the cap, the packing will be pressed to closed iteration.
Excellent of sealed peculiarity: It has excellent flexibility and plasticity because Expand PTFE’s individual structure. PTFE valve stem filling is easy to stuff up inside gap even possession cave and gutter on the valve lever, the valve which have be corroded not need to change or repair.
Durable: Because it keep flexibility long term and caulk the gap at any time, also resistant corrode and resistant ageing, it is durable!
Easy to open and close the valve: Because PTFE has the peculiarity of low rub factor and excellent lubrication self and it won’t pollute fluid in pipe, Expand PTFE Packing is especially suitable the flied of medicine, grocery, electro because of it’s clean.
Economy: You only equip packing with several specifications and it will enough for valve. Usually we choose the most biggest packing which can built-in with hand, but the tenuous packing also be use in valve with big size, it just be pressured.
Technology:
suitable temperature -100～+260℃
suitable pressure ＜20Mpa
Suitable medium: every chemistry matter but F and melt alkali metals.
Specification: diameter (mm) 3 4 5 6 7 8 10 12 14 16 18 20
packing: reel on plastics axle and 1kg/roll or 5kg/roll |
