BODY FILL VLV W/SCREEN SC

A screen is physical divider intended to block an area from view or to block access.  Screens often provide protection or even filtration and may have holes or perforations allowing air or liquid flow.  A screen may also refer to a "touch screen" which provides a graphical user interface (a display device) which allows the user to interact with a computer or control by touching areas on the screen. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.

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.
