SPRING SHUTOFF VALVE

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.

A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. There are many spring designs. In everyday use, the term often refers to coil springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length.

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.
