GasMultiBloc MB-D(LE) and MB-ZRD(LE) 403–420 — "filter + regulator + two valves" multiblocks, up to 36 kPa
Country: Germany · Model: GasMultiBloc MB-D(LE), MB-ZRD(LE) 403–420
The GasMultiBloc MB combines a strainer filter, a pressure regulator and two solenoid valves in one assembly, with maximum working pressure of 360 mbar (36 kPa). The MB-D(LE) and MB-ZRD(LE) series in sizes 403–420 replace a gas train of separate devices on forced-draught burners, boilers and process heat generators.

Description
The valves are made to EN 161 class A group 2, and the proportional regulator to EN 88 class A group 2. Depending on the spring, the outlet pressure is adjustable from 4 to 20 mbar (S20/S22) or from 4 to 50 mbar (S50/S52). The solenoids are DC; valve V2 has a main flow limiter and a hydraulic opening delay. The connection is a flange with pipe thread to ISO 7/1, from Rp 3/8 to Rp 2 and combinations of them. MB-D(LE) works in single-stage mode, where both valves are fast-opening or one is fast and one slow. In MB-ZRD(LE) one valve is single-stage and the second is two-stage with adjustment of main and partial flow; for liquefied gas a regulator lock is provided. The modular system allows an external pilot gas outlet, VPS 504, GW…A5 switches, pressure limiters and a limit switch on V2. The media are gases of families 1, 2 and 3 and other neutral gases.
How to choose
The type is chosen by burner mode. MB-D(LE) is fitted on a single-stage burner, MB-ZRD(LE) on a two-stage one. The series is made in B01 and B07 versions, and separate datasheets exist for sizes 403, 405–412, 407–412 B07 and 415–420. Springs S20/S22 or S50/S52 are selected by the required outlet pressure.
