Fire Safety Valves,Check Valves, andThermal Switches

Fusible Fire Safety Valves are designed to reduce fire damageby shutting o� the flow of oil from the oil tank in the event of afire. Valves such as these are required by code in residential oilheating installations in conformance with NFPA 31. Thesevalves conform to cULus MH 46634.

All valves are embossed with an arrow indicating the directionof oil flow. The seal stem uses a double seal washer/o-ringsystem with high grade Viton® equivalent materials suitable forNo. 2 fuel oil and Kerosene. Maximum pressure rating is 10PSI.

Lever Valves

The Lever Valve o�ers added protection in certain situations. It is sometimes used at the Tank and held open by a spring loadedflexible wire in which fusible links are set. If the temperature at the link reaches standard temperature (165°F), the links will pullapart and the valve will immediately close, stopping the flow of oil. (All accessories shown below are included).

Accessories furnished with each each Lever Valve: take-up spring, coil of braided wire, two fusible links (set at 165°F) and two

Thermal Switches

Thermal switches – A safety device which provides added protection to fuel burner installations. It is a thermally operated switchinstalled in the electrical power line to the burner. It is normally set at 165 degrees F and removes power if the ambient temperaturereaches this point. The burner then shuts o� immediately. The thermal switch is usually positioned on the ceiling, close to theburner. It SHOULD NOT be used manually to start and stop the burner. When properly installed, there are no exposed electricalwires or contacts, before or a�er firing – this is important. The fusible element is the hand wheel of the switch – a�er it ‘fires’, simplyreplace the hand wheel to restore the switch.

LineGuardian




Advanced Fire Protection

The LineGuardian valve system protects your fuel source in the event of a fire. The unique built-in fire-safety features include fuse-able plugs at both ends of the fuel line (valve and termination fitting), as well as a new fuel line technology that triggers the valve tostop the flow of oil from the tank in the event of a fire.

Features & Benefits

Full line protection, from valve to terminationFire protectedPurely mechanical valve, intrinsically fail-safeNo electricity or calibration requiredContains manually operated service shut o� valve




Can be used instead of an anti-siphon valve and does not require a vacuum to openFuel line has exceptional flexibility, will not crack or break under repeated bendingFuel line provides secondary fuel containmentSuitable for both indoor and outdoor installations, above or below groundEasy to implement and cost e�ective solution5-Year manufacturer’s warranty

Stop Fuel Line Leaks at the Source

LineGuardian is not a spill containment system, but a leak prevention system. By stopping the leak before it becomes anenvironmental incident, the homeowner, business, insurance provider and the community can realize the benefits of the system.
