Operating conditions Fig. 1Merkel Packing Ring TFW made of PTFE PressureTemperature 31,5 MPa–200 … +220 °C Product description Running speedon axial movementon rotary movementContinuous operation V-shape sealing ring made of PTFE for making up packings, comprising:1 saddle ring TFS 3 to 5 angled rings TFW 1 mating ring TFG.Note: Only TFW rings are available from stock. Complete packings are only available on request. approx. 0,5 m/sapprox. 0,2 m/s Intermittent operation approx. 1,5 m/sapprox. 0,4 m/s Product advantages NN N Packing rings TFW feature very good chemical and thermal resistance, low fric- tion and favourable breakaway forces even after long periods of down-time. Fitting installation Application With fluctuating operating temperatures or when sealing a rotating shaft, the packing is to be pre-loaded with 1,5to 2 N/mm Packing rings TFW are suitable for axi-ally operated valve spindles, rods and plungers, as well as slowly turning shafts. 2 on the pressure side using a spring. If the spring must be installed on the non-pressurised side then its pre- load is to be matched to the maximum pressure that occurs. If metal saddle and mating rings are manufactured by the customer, the dimensions are to be taken from the table. The number of PTFE angled rings depends on the pressure of the medium.We recommend: p ≤ 3MPap 3 10MPap 10MPa 3 TFW4 TFW5 TFW © Freudenberg Simrit GmbH & Co.
