10 Fuel Fill Spill Containers Model 1 In Ground Spill Container Drains oil spilled from delivery disconnect into storage tankDesigned to handle driveway trafficRemovable bellows for easy fuel testing without pavement excavation.
11 Fuel Fill Model 2 In Wall Spill Container For indoor storage tanks withfill lines to building wallsStandard models from simplebox to integrated digital leveldisplay and overfill alarmingWe can customize many things: A bronze Model 2 was recently installed at Radio City Music Hall to contribute to the building’s décor.
19 Anti-Syphon ValvesUsed where fuel leaks will result in fuel being syphoned into areas which can cause a dangerous and costly situationUL Labeled and listedFor No. 2 through No. 6 Oils5’, 10’, 15’ or 20” Head SelectionInstalled at highest point in piping
20 Fire Safety Shut-off Valves Preferred’s Lever Gate ValveFully mechanicalEmergency fuel line shut-off is mandated by many codesFusible links open at 165Ffor pipe ranges 1" - 3"Fusomatic ValveReplaceable fusible elementFusible links open at 165F, May be manually opened/closedfor pipes 3/4" or 1"
22 Foot ValvesEnsures maintenance of pump prime by preventing oil backflow into the tank when pumps are offSingle Poppet1/2” to 3” SizeDouble PoppetDouble the protection1-1/2” or 2” SizesFoot Valve Extractor FittingEasy Removal and Inspection of Foot Valve
