The modulating control valves of the newly conceived MDV-D1 series are built according to the EN 161 norms to be used on industrial combustion systems. They are particularly suitable for the proportional regulation of all 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. The exact linear rating is achieved by means of particular, patented shutter disks, rotating on the same axis. Six different orifice sizes are available according to the operating conditions. MODULATING CONTROL VALVES Series MDV-D1 (Modulating Disc Valve) Electric gear motor separated from the gas flow Sturdy, compact construction, especially suitable for industrial applications Installation in any position Mechanical position indicator Adjustable rotation angle Manual/automatic operation and service switch Open/Stop/Closed with relay for cut phase Wide range of accessories on request: 1 or 2 potentiometers ranging from 150 ohm to 2,5 kohm 2 adjustable auxiliary microswitches with free electric contacts input control signal: 4÷20 mA or 0÷10 Vdc (Supply voltage 24Vac/50-60Hz) auxiliary shaft with 8 mm ø or with 9,5 mm square shaft Construction Group Control device Ambient temperature Opening/closing time Operating pressure Flanged connections Rating feature Control ratio : die-cast aluminium : 2 : without zero setting : -10 ÷ +60 °C : 30 s or 60 s / 90° : max. 1 bar : ISO 7500 - PN 16 : linear : 25:1 Base and cover Supply voltage on request Nominal load Enclosure Duty cycle Trip and auxiliary switch rating Potentiometer/s Cable gland Input signal : die-cast aluminium : 230 Vac / 50-60 Hz : 115 Vac / 50-60 Hz o 24 Vac / 50-60 Hz : 7 VA : IP 54 secondo IEC 529 : continuous 100% : 5 (1) A/250 Vac : 150; 1000; 2500 Ù : 2 x Pg 13,5 : 4 ÷ 20 mA o 0 ÷ 10 Vcc TECHNICAL DATA FEATURES Valve Gear motor
