The PS is mounted on the\noutlet side of the ValveBody.\nThe outlet pressure is meas-\nured by the PressureSensor\noutlet side or downstream of\nthe VB. The pressure signal is\ntransmitted to the VD-R via the\nBUS cable. The nominal value is\npre-adjusted manually.\n\n\n\n\nMBE Edition 01.25 294 594 5 ... 24\n\fMBE technical data\n\n MultiBloc® Generation E multifunctional control\n Nominal diameters VB-050:\t\t\t Rp 1½ - 2\n VB-065 to VB-150: DN 65 - 150\n VB-2L:\t\t\t NPT 1½ - 2\n VB-2½L to VB-6L: NPS 2½ - 6\n\n Maximum inlet pressure VB-050 \t\t\t pmax. = 60 kPa (600 mbar)\n VB-065…150\t\t pmax. = 70 kPa (700 mbar)\n VB-2L\t\t\t pmax. = 8 PSI (240 \"W.C.)\n VB-2½L…6L\t\t pmax. = 10 PSI (280 \"W.C.)\n\n Outlet pressure range Only in combination with VD-R… and PS-…\n PS-0:\t\t\t 0 kPa / 0 \"W.C.\n PS-10/40: \t\t 0.4-10 kPa / 1.6-40 \"W.C.\n PS-50/200: \t\t 2.0-50 kPa / 8.0-200 \"W.C.\n\n Accuracy class ± 5 % or ± 50 Pa (as per EN 88-3)\n\n Opening time approx. 6 sec. until 100 % open\n\n Closing time < 1 sec.\n\n Switching rate max. 360/h\n\n Ambient temperature -20 °C to +60 °C\n\n\n\n\nMBE Edition 01.25 294 594 6 ... 24\n\fMBE technical data\n\n MultiBloc® Generation E multifunctional control\n Process liquids / gases As per EN 437:2018\n Suitable for gases of gas families 1,2,3, 100% hydrogen (dry), bio and digester gases\n (DVGW G 260 (A)) up to max. 1.0 vol. % H2S (dry).\n Do not operate the MBE… below 0 °C in liquid gas systems.
