Ask Baumer Gold, 15 ųm thickness • Capillary with low-temperature controlled electric heat tracing • Improve response time for long capillary • Decrease in effects of outside temperature: at -40 °C capillary tube temperature over +30 °C at +40 °C capillary tube temperature below +60 °C • Approx. Ø 25 mm heat insulation • Sealed outer sheath Option 1940. The D914 chemical seal can be delivered in 4 parts unassembled - the counter flange - the chemical seal - the RTJ joint - the process flange with the bolting and the valves (according to versions) Data sheet A42.06 Page 1 / 3 2015-10-15 • 0393 mounting on high pressure side (HP) 1) • 0385 mounting on low pressure side (LP) 1) Design and specifications subject to change without notice Options D914 Flanged chemical seals Dimensions (mm) 149 (DN20) 159 (DN50) OD10 or OD3/8” (Option) Vent valve 267 39 Hanger ring 1/ 4 sc h. 80 50 . ox pr ap 2 23 1/4 sch.80 50 Nx L1 approx. 232 K Steam tracing 1/4NPT Drain valve OD10 or OD3/8” Flange dimensions (mm) DN Class ØK ØL1 ISO ØL1 ASME N Weight kg N° GRTJ(1) 20 1500 88.9 M20 3/4" UNC 4 58 R 14 1500 101.6 M24 7/8" UNC 4 62 R 16 1500 123.8 M27 1" UNC 4 63 R 20 1500 165.1 M24 7/8" UNC 8 65 R 24 3/4" 25 1" 40 1"1/2 50 2" (1) Number of the RTJ groove in case of RTJ flange on process side.
