Description
MN28 has Rp DN 20, 25, 32, 40, 50 threads or DN 25, 32, 40, 50 flanges for PN 16, and the operating pressure of 4, 6 or 8 bar (400–800 kPa) depends on the size and voltage, with fuel viscosity up to 8 °E. The supply is 24 V, 110 and 230 V 50–60 Hz, the cable entry is M20×1.5, and the temperature is from −5 to +60 °C. M15-1 is a compact valve for diesel fuel, Rp DN 10 and 15, bore 5.6 mm, pressure 4 bar, supply from 12 to 230 V, IP65. Both valves are registered under PED 2014/68/EU and comply with EMC, LVD and RoHS II. SOF filters are rated for 4 bar and SOFM for 15 bar, with an operating temperature up to +150 °C. Connections are Rp DN 15–50 per EN 10226 and PN 16 flanges DN 40 and 50, a G 1/2 drain plug on small sizes, and G 1/4 pressure gauge ports on DN 40–50. Filtration is 100, 300 or 600 µm for DN 15–40 and 250, 500 or 750 µm for DN 50.
How to choose
MN28 is used for fuel oil and diesel fuel with viscosity up to 8 °E, and M15-1 for diesel fuel in small diameters. The filter is chosen by pressure (SOF up to 4 bar, SOFM up to 15 bar) and filtration fineness. On request an electric heater for viscous fuel oil, a magnetic column and a self-cleaning servo drive are added. This item belongs to the fittings of liquid-fuel burners, not gas ones.
