Fusible Plug

Product Description

Air type fusible plugs are used to protect compressed air systems from the risk of an explosion occurring due to ignition of oil vapours in compressors and compressed air systems.

Boiler type fusible plugs are used to protect solid fuel fired boilers from being operated at dangerously low water levels.

Both plugs are designed to operate when high temperatures occur, thereby reducing pressure and providing audible warning of dangerous conditions.

They are made of brass or bronze construction with a centrally located fusible disc. When fusion occurs, air pressure ejects the molten disc which is retained by a vented cap.

The fusing temperature of the disc is chosen to suit working conditions. When specially ordered, stainless steel and high pressure versions of both FP Valves can be supplied.
