VALVE PILOT SHUTOFF

A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. In a pilot assembly, there is thermocouple sitting in the pilot light's flame. The electricity that is created from the flame contacting the thermocouple wire runs to a small electromagnetic valve and holds it open. If the pilot light blows out, the thermocouple quickly cools off. It stops generating electricity and the valve closes.

A shutoff is a device (a gate, valve, shaft, cam or breaker) designed to interrupt the flow of a solid, liquid, or a gas and in electrical components, the flow of current. Shutoffs may also be used as brakes in slowing or stopping the motion of a system or component. Shutoffs may be manually or automatically actuated in response to connected signaling or sensing systems.

Valves are widely used in different restaurant equipment designs. A valve is a device that regulates, directs or controls the flow of a fluid (gases, steam, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. In an open valve, fluid flows in a direction from higher pressure to lower pressure. 

Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow, allowing control over a variety of operational requirements.
