Fire Valves

Fire valves are an essential safety device to be installed on any fuel line feeding oil-burning equipment. They are designed to prevent the spread of fire by shutting off the flow of oil to the burner if overheating or uncontrolled fire is detected. They can also be configured to open, in order to dump oil. 

Hytek sells drop-weight valves; these can be mounted on either horizontal or vertical pipework and operate purely mechanically so there are minimal points of failure. They work by simply using wire to hold up a weight that, if released, moves a level to close or open the valve. The wire contains fusible links and is strung in such a way that these links are close to the oil burner. In the event of a fire or the burner overheating, the links will melt, breaking the cable and causing the weight to fall. This either closes the valve, blocking the flow of fuel, or opens a dump valve causing it to spill out well away from the burner. 

These drop-weight valves are reliable and easy to install, and are suitable for use with oil or gas at pressures of up to 14 bar. They come packaged as a complete kit including a range of cables, fusible links, pulley wheels, tension springs, connectors and warning signs so that the valve can be set up in any number of different configurations.
