The FEL Valves range of Free Fall Fire Valves are suitable for installation in either horizontal or vertical pipe work, and are designed to\u00a0 provide a positive, 100% shut off when used as a fuel isolating valve, or\u00a0 opening, when used as a fuel dump valve. A standard Free Fall Valve assembly\u00a0 comprises of a valve, lever and weight, together with a fitting kit.<\/p>\n

\"\"<\/p>\n

All standard valves are manufactured in cast iron to ASTM A126 Gr B and are approved by both the American Gas Association and Canadian Gas\u00a0 Association, as well as being \u2018UL\u2019 listed. All valves are suitable for use with\u00a0 fuel oils and gases at pressures up to 14 bar. Valves with screwed connections\u00a0 have BSP parallel threads, whilst flanged valves are available with either BS 4504 PN 16 flange drillings or to ANSI 125. FEL Free Fall Fire Valves are also available with carbon or stainless steel body and plug materials.<\/p>\n

Standard Fire Valves are supplied with a \u2018650 Lubricating Compound\u2019, which is a general purpose sealant, suitable for hydrocarbons, other\u00a0 Lubricating Compounds are available, if you are unsure of the suitability of the 650 Compound for your specific application, please contact us for further\u00a0 details.<\/p>\n

Free Fall Valves may be actuated mechanically or electrically. The majority of installations use mechanical actuation by fusible link,\u00a0 therefore each Fire Valve is supplied with a Fire Valve Kit, available in three sizes, Small (15 to 50mm valves), Medium (65 to 100mm valves) and Large (125 to 200mm valves). Kits contain varying numbers of Pulley Wheels, Stainless Steel\u00a0 Cable, Fusible Links, Warning Signs, Cable Connectors and Tension Springs, any\u00a0 of which may be purchased as individual products.<\/p>\n

Electrically actuated Fire Valve systems utilise a standard\u00a0 valve, lever and weight, however an electrical Release System is used, essentially, allowing actuation by making or breaking an electrical circuit. The\u00a0 installation of a valve mounted Mercury Switch, Electro Mechanical Release or Wall Mounted Changeover Switch may provide remote signaling of the Fire Valve\u00a0 status, or allow direct switching of electrical equipment where applicable.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
