  6. Fuel Fill Model 1 (Catalog 23, p63) • Spill Containers • Model 1 In Ground Spill Container • Drains oil spilled from delivery disconnect into storage tank • Designed to handle driveway traffic • Removable bellows for easy fuel testing without pavement excavation.

  7. Fuel Fill Model 2 (Catalog 23, p61) • Model 2 In Wall Spill Container • For indoor storage tanks with fill lines to building walls • Standard models from simple box to integrated digital level display and overfill alarming • We can customize many things:A bronze Model 2 was recently installed at Radio City Music Hall to contribute to the building’s décor.

  8. In Wall Spill • We required that all components in the alarm station be of explosion proof construction including the alarm horn, alarm light, silencing push-button and digital remote readout (if required). • Explosion proof components are required for safety and to prevent the ignition of the fuel oil vapors generated from the sun heating the spill container. Catalog 23 Page 61

  11. Vent • Vent Caps & Bricks • Standard Tank Vent Protectors for storage tanks • Conform to Standards for the Installation of Oil Burning Equipment (NFPA No. 31) Vent Cap (Catalog 23, p68)

  12. Vent • Vent Bricks provide a terminal for indoor storage tank vent lines • Standard masonry brick size • Fits 2" & 3" vent lines Vent Brick (Catalog 23, p68)

  14. Anti-Syphon Valves • Patented by Preferred Utilities. • UL Labeled & Listed Catalog 23, p74

  15. Anti-Syphon Valve Manifold

  16. Anti-Syphon Valve • In addition to requiring a UL listed valve we now require a Bronze valve rather than a cast iron • We state the ability of bronze not to crack or fail in a fire condition. • We have also explained the importance of the valve. • It is too important to substitute. • We want to get the sale when we get the system or not. We are the only ones that make a ½ & ¾ version. Catalog 23 Page 74

  17. Anti-Syphon Valves • Used where fuel leaks will result in fuel being syphoned into areas which can cause a dangerous and costly situation • UL Labeled and listed • For No. 2 through No. 6 Oils • 5’, 10’, 15’ or 20” Head Selection • Installed at highest point in piping

  18. Fire Safety Shut-off Valves • Lever Gate Valve • Fully mechanical • Emergency fuel line shut-off is mandated by many codes • Fusible links open at 165F • for pipe ranges 3/4" - 3" • Fusomatic Valve • Replaceable fusible element • Fusible links open at 165F, May be manually opened/closed • for pipes 3/4" or 1" Model 110 with alarm switch (Catalog 23, p72) Fusomatic Valve (Catalog 23, p71)

  19. Type 110 Fire Valve

  20. Foot Valves • Ensures maintenance of pump prime by preventing oil backflow into the tank when pumps are off • Single Poppet • 1/2” to 3” Size • Double Poppet • Double the protection • 1-1/2” or 2” Sizes • Foot Valve Extractor Fitting • Easy Removal and Inspection of Foot Valve

  21. Foot Valves Model 900 (Catalog 23, p77)

  22. Level Control Arrangement Vent Emerg. Gen. Day Tank with Rupture Basin Fill Return Supply Suction Pump Main Oil Tank

  23. Relief Valves • Very important for use on positive displacement pumps • Sizes for 1/2” to 3” • For use with any type oil • Pressure Ranges of 5-35psi, 25-100psi, 75-300psi

  24. Level Control Arrangement Vent Emerg. Gen. Day Tank with Rupture Basin Fill Return Supply Suction Pump Main Oil Tank

  25. Fuel Components • Tank Selector Valves • Replaces confusing array of hand valves • Simple lever operation transfers both supply & return lines from one tank to the other • Designed with no “blind spots” where flow could be blocked to or from the tanks • Threaded or flanged connections available Threaded Connection (Catalog 23, p81)

  26. Back Pressure Regulating Valves • Used in a flow loop to maintain proper pressure for burners. • Type BQ for flow rates up to 390gal/hour • Standard Ranges of 26-75psi or 76-150psi • 1/2” Size • Type V for higher flow rates • Standard Range of 30-150psi • 1” Size

  27. Strainers • Duplex • No flow interruption for routine cleaning • 90° handle movement switches baskets • Handle blocks inadvertent opening of active side • Sizes from 3/4" - 6" • Simplex • Special yoke design for quick cleaning • Large basket • Sizes from 1/2" - 2" Duplex Oil Strainer (Catalog 23, p43)

  28. Pump Sets Components • Multiple pumps share common suction and discharge piping • Most common is duplex set • two 100% pumps, one for backup • control system can monitor flow, start lag pump • Triplex pump sets for large plants • three 50% pumps allow for one spare • two 100% “winter pumps” - one 50% “summer pump”
