Linear modulating valves

Modulating valves LMV are used in combustion processes that require linear adjustment of air or gas flow.
The flow varies proportionally to the opening angle of inner mechanism, therefore flowrate is very predictable.

The valve can be operated with stage control (3-point, MZ3 servomotor) or with continuous modulation (analogue signals, MZ5 servomotor).

LMV is available with full gas orifice or reduced gas orifice.
