It is designed for\nuse as an interrupter valve or as a shut-off valve in fuel\noil burners or manufacturing processes.\nThe body is fabricated of brass, the plunger is of\nmagnetic quality steel and the seal is a synthetic rubber\nwhich is suitable for use with light distillate oils and other\nfluids that are compatible with the above materials.\n\n\n\n2- Technical specifications Model with\nOil temperature: .................. 60°C max connector plug\nMax. operating pressure: … 25 Bar\nAmbient temperature: …….. 0°C / +60°C 5- Mounting\nOpening response: ………... Instantaneous cut-off\n (open when energized) • Check the direction of flow with the arrow printed on\nPower consumption: ……… 9 W the valve body.\nProtection class: ...……….... IP65 • Check correct alignment of connecting pipes.\nFlow factor (Kv): ………….... 0,08 m³/h • Do not use the valve stem to turn the unit onto the\nOrifice: ……………………..... Ø2 mm piping.\nWeight: …………………….... 200 g • Valve may be mounted with coil in horizontal or\nFluids: ……………………….. Kerosene, heating oil EL, vertical position. Do not install upside-down.\n Diesel, K1, #1, #2 fuel oil • By releasing the nut on top of the valve, the coil may\nConnections: ……………….. G1/8 MF be oriented 360 degrees in any direction.\n G1/8 FF • Install in an area that is protected from rain and\n R1/8 M-G1/4 M water splashes or drops.\n FF 1/8” NPTF • Do not use PTFE tape in the connections.\n MF 1/8” NPTF • An external filter must be always installed upstream\n the valve.\n • Protection against accidental touch of hot coil must\n be provided by appropriate installation.\n3- Materials and construction\nBody: ………………………....
