Fisher 3000-5002 Gasket Waste Valve

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Sheet gaskets are used to create custom gaskets. Cam-and-groove gaskets provide a tight seal between couplings in low-pressure fluid applications such as regulators and pumps. Sanitary gaskets are used in piping systems for the food and beverage industry.

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. These changes may act upon a diaphragm or a piston which in turn activates the valve. More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately and allowing control over a variety of requirements.
