VALVE EXPANSION 3 ORIFICE R404A R448A

An orifice is any opening, mouth, hole or vent, as in a pipe, tube or a plate used to either regulate or measure the intake or output of a gas or liquid, e.g. "air orifice", or "orifice plate".

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.
