6 The downstream pressure is regulated, this means the valve closes when the downstream pressure fields are to regulate fluids of the group II acc. to Pressure Equipment Directive 2014/68/EU, steam, neutral gases, vapours and liquids. With steam and liquids, having temperatures higher than the allowable working temperatures a water seal pot must be installed in the control line (to protect actuator diaphragm) (refer to page 6).Installation in the control line can be seen in the system drawing:Bypass pipeFABA-PlusSAFED ownstream pressure manometerInlet pressure manometerSeparatorFABA-PlusStrainer (Fine screen)Flow indicatorCONA S Ball float steam trapCONA B Bimetallic steam trapFlow indicatorControl lineFABA-PlusWater seal potFABA-PlusPREDU Pressure reducing valveFABA-Plus10 x DN / min. 1m SizingFor the calculation you have the program myValve (Program part Pressure reducing valves ).

7 After giving in the process data, the and size is recommended out of the integrated data bank. The diameter of the piping in front and behind of the pressure regulating valve can also be calculated with the max. allowable flow velocities with necessary downstream pressure gives the needed pressure range. Because the regulation tolerance at the end of the range is smaller, the smaller range must be used, in case of a range overlapping. For example: Downstream pressure 2,4 bar(g), choose actuator range 0,8 - 2,5 bar(g), although 2-5 bar(g) could be safety valve used to secure the downstream pressure must have an adequate distance between set pressure and downstream pressure. The max. possible capacity of the pressure reducing valve is used to select the safety valve at it s set pressure. The max. possible capacity has to be calculated with p1 (= max. possible inlet pressure), p2 (= set pressure of the safety valve) and the Kvs-value of the pressure reducing valve with myValve.

8 With this found capacity you can, with myValve (Program part: Safety valves), select the safety valve, and with the pressure reducing valves and other valves, administer them under a : If not secured that the bypass valve has a larger capacity than the pressure reducing valve, or that it can be open parallel, then the extra capacity must be considered for the safety valve 08/19 - Data subject to alteration - Regularly updated data on !ARI-PREDU Fig. Fig. Fig. Fig. , EN-GJL-250EN-JS1049, EN-GJS-400-18U-LTGP240GH+N, +NGX5 CrNiMoNb19-11-2, seat ring X20Cr13+QT, +QTX6 CrNiMoTi17-12-2, , -A2BA4-704xGasket Pure graphite (CrNi laminated with graphite)5 Bush housingEN-JS1049, EN-GJS-400-18U-LTX6 CrNiMoTi17-12-2, bushX20Cr13+QT, +QTX6 CrNiMoTi17-12-2, Pure graphite (CrNi laminated with graphite)8xBalanced-bellow-unitX6 CrNiMoTi17-12-2, / X5 CrNi18-10, / X20Cr13+QT, +QTX6 CrNiMoTi17-12-2, +QT, +QT (hardened)X6 CrNiMoTi17-12-2, (hardened)10 WasherA2A411 Hexagon screw< DN40: A4-7011 Head DN40: X6 CrNiTi18-10, / X20Cr13+QT, +QT DN50: X6 CrNiTi18-10, >DN50: X6 CrNiTi18-10, /X6 CrNiMoTi17-12-2, Fig.
