Description
MBC-65 and MBC-120, 105 mm long, are intended for single-stage operation; their maximum pressure is 200 and 360 mbar (20 and 36 kPa), and the N versions are rated for 65 and 100 mbar. The valves are class A to EN 161 (group 2), the regulator is servo-controlled to EN 88 class C, with zero or constant pressure, fast or slow opening and a main flow limiter. Ambient temperature is from −15 to +60 °C. MBC-300, MBC-700 and MBC-1200 in SE and N versions work at 360 mbar with an outlet pressure of 0–80 mbar (0–8 kPa) for modulating burners with mechanical or electronic gas/air ratio control. VEF versions have a pneumatic ratio of 0.4:1…3:1, an outlet up to 300 mbar, zero correction and an internal gas line. Connection is by ISO 7/1 flanges or NPT. The WhirlWind system (MBC-WND) combines a swirl plate, a Venturi tube and a signal amplifier for burners from 9 to 1000 kW, with inlet pressure of 65 mbar for WND 65 and 100 mbar for WND 120–1200, and modulation up to 1:10.
How to choose
If the burner is single-stage and space is limited, MBC-65 or MBC-120 is taken. For a modulating burner with an external ratio system, MBC-300, 700 or 1200 in the SE or N version is suitable, and when the multiblock itself must hold the ratio, the VEF version. For premix and forced-draught burners without selecting an injector for the gas family, MBC-WND is taken. Pressure switches and VPS are added separately. For the USA there are MBC-1000/2500/4000 in the SE, VEF and VV variants.
