STEM VALVE W/O O-RING

O-rings are used in various types of restaurant equipment to create a seal between two connected parts, preventing leakage of product, liquids or gases:

• Espresso Machines: O-rings are used to seal the group head and the portafilter, ensuring that hot water and steam are directed into the coffee grounds to produce espresso, and not leaked out.
• Refrigeration Systems: O-rings are used to seal the refrigerant lines and connections in refrigeration systems, preventing refrigerant leakage and ensuring that the system operates efficiently.
• Beverage Dispensers: O-rings are used to seal the connections between the beverage dispenser and the beverage container, ensuring that the beverage is dispensed without any leakage.
• Dishwashers: O-rings are used in dishwasher pumps, ensuring that water is properly circulated and does not leak or flow in the wrong direction.
• Fryers: O-rings are used to seal the connections between the gas supply and the burner in fryers, ensuring that there is no gas leakage and preventing potential safety hazards.

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.
