VALVE PISTONTD2 USED AFTER 0

A piston is a component part of reciprocating motors, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms which are widely used in restaurant equipment. The piston is the moving component that is within a cylinder and is sealed by piston rings (o-rings, gaskets, etc.). The piston within the pump compresses and ejects a gas or liquid.

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.
