Combination of PTFE valve seat ball valve seat PTFE seal ring PTFE gasket:
PTFE has excellent high and low temperature performance and chemical stability, good electrical insulation, non-adhesion, weather resistance, non-combustion and good lubricity. PTFE was developed for national defense and technical needs, and then gradually expanded to civilian use. Its uses involve industrial sectors such as aerospace, petrochemicals, machinery, electronics, construction, and textiles. It is an indispensable material for solving many key technologies and improving production technology of modern science and technology, military and civilian use. The characteristics of PTFE are unmatched by other plastics, and it is known as the "king of plastics".
PTFE has some special properties:
Corrosion resistance-able to withstand all strong acids except molten alkali metals, fluorinated media and sodium hydroxide above 300 ° C
(Including aqua regia), strong oxidants, reducing agents and various organic solvents.
Very strong insulation resistance-not affected by environment and frequency, volume resistance can reach 1018 ohm • cm, small dielectric loss, high breakdown voltage
Excellent resistance to high and low temperature-little effect on temperature, wide temperature range, applicable temperature -190∽260 ℃.
Self-lubricating-with a relatively small friction coefficient in plastics, it is an ideal oil-free lubricating material.
Prominent surface is not sticky-none of the known solid materials can adhere to the surface and is a solid material with a relatively small surface energy.
Excellent resistance to atmospheric aging, radiation resistance and low permeability-long-term exposure to the atmosphere, the surface and properties remain unchanged.
Valuable non-combustibility-oxygen limit index is below 90.
Other parts for reference:
Cangzhou Cencho Tech Solution Co.,Ltd is mainly engaged in supplying all kinds of stainless steel ball valve, valve accessories, stainless steel pipe fittings and customized stainless steel parts. For some of our customers, they would like to buy the valve accessories back to their workshop and then assemble all parts by themselves, then sell the complete stainless steel ball valve to their distribution all over the world, but with very lower cost. So if you have same idea, you can also do like that, we still are able cooperation with you in that way.
The valve accessories we can provided include valve ball, valve handle, handle plastic cover, PTFE seat/ gasket/ seal, stem, gland nut etc.
Any interest for any part of them, please feel free to contact us!
