Therefore, request the plug and teflon sleeve surface roughness value must be small, its geometry error must be small, also can achieve the required pressure seal. If the seat sleeve need to pressure in order to restore the sleeve sealing, must be in a yellow to shut off the Industrial Valves to prevent the teflon casing pressure flow within the tao.
