The control valves of the newly conceived MPV series are DVGW approved to the Norm EN 161 and with CE product identification to meet requirements in industrial and residential combustion systems. They are particularly suitable for the proportional adjustment of combustion gas flows of the first, second and third family and of air. The electric motor is unipolar and bidirectional, with high static and maintaining torque for 3-position-control, or proportional with analogic input control signal: current or voltage change. A cylindrical plug, linear featured, regulates the flow rate of the valve. By cylinder rotation, the orifice size of the plug changes with, adjusting the flow linearly. Three different orifice sizes are available according to the operating conditions.
