To compensate the normal prestress loss due to the seal materials, you have to use also disc springs in addition to the flange screws for fastening PTFE plated flanges. We recommend flexible retaining washers (e.g. Schnorr VS or S) or detent edged rings (e.g. Gross VS KD). Fig. 9: Use of disc springs Single disc spring Laminated disc spring The flange screws of SITRANS LG240 must be tightened with a torque of approx. 60 Nm (44 lbf ft) so that the PTFE washer seals reliably.
