Fire Safety Valves, Check Valves, and Thermal Switches

Fusible Fire Safety Valves are designed to reduce fire damage by shutting off the flow of oil from the oil tank in the event of a fire. They are required by code in residential oil heating installations in conformance with NFPA 31.

All valves are embossed with an arrow indicating the direction of oil flow. The seal stem uses a double seal washer/o-ring system with high grade Viton® equivalent materials suitable for No. 2 fuel oil and Kerosene. Maximum pressure rating is 10PSI.

Lever Valves

lever valves

 

The Lever Valve offers added protection in certain situations. It is sometimes used at the Tank and held open by a spring loaded flexible wire in which fusible links are set. If the temperature at the link reaches standard temperature (165°F), the links will pull apart 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 Pulleys.  212°F links available (purchased separately).

Thermal Switches

thermal switches

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

Contact ratings:

  • Pilot 120 volts, 60 Hz, 360VA.
  • ½ Horsepower, 12 volts, 60Hz.

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 to stop the flow of oil from the tank in the event of a fire.

Features & Benefits

  • Full line protection, from valve to termination
  • Fire protected
  • Purely mechanical valve, intrinsically fail-safe
  • No electricity or calibration required
  • Contains manually operated service shut off valve
  • Can be used instead of an anti-siphon valve and does not require a vacuum to open
  • Fuel line has exceptional flexibility, will not crack or break under repeated bending
  • Fuel line provides secondary fuel containment
  • Suitable for both indoor and outdoor installations, above or below ground
  • Easy to implement and cost effective solution
  • 5-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 an environmental incident, the homeowner, business, insurance provider and the community can realize the benefits of the system.
