2. Hydraulic manifold - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_manifold

   A manifold is composed of assorted hydraulic valves connected to each other. It is the various combinations of states of these valves that allow complex control behaviour in a manifold. [1] [citation needed] A hydraulic manifold is a block of metal with flow paths drilled through it, connecting various ports. [2]

3. Block and bleed manifold - Wikipedia

   en.wikipedia.org/wiki/Block_and_bleed_manifold

   Two block valves and a bleed valve are as a unit, or manifold, to be installed for positive isolation. Used for critical process service, DBB valves are for high pressure systems or toxic/hazardous fluid processes. Applications that use DBB valves include instrument drain, chemical injection connection, chemical seal isolation, and gauge isolation.

4. Manifold (fluid mechanics) - Wikipedia

   en.wikipedia.org/wiki/Manifold_(fluid_mechanics)

   Types of manifolds in engineering include: Exhaust manifold An engine part that collects the exhaust gases from multiple cylinders into one pipe. Also known as headers. Hydraulic manifold A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps Inlet manifold (or "intake ...

5. Exhaust manifold - Wikipedia

   en.wikipedia.org/wiki/Exhaust_manifold

   When the exhaust valve opens, the high pressure exhaust gas escapes into the exhaust manifold or header, creating an "exhaust pulse" comprising three main parts: The high-pressure head is created by the large pressure difference between the exhaust in the combustion chamber and the atmospheric pressure outside of the exhaust system

6. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   The valve can use a two-port design to regulate a flow or use a three or more port design to switch flows between ports. Multiple solenoid valves can be placed together on a manifold. Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids.

7. Valve - Wikipedia

   en.wikipedia.org/wiki/Valve

   Examples of normally-closed valves are sampling valves, which are only opened while a sample is taken. Other examples of normally-closed valves are emergency shutdown valves, which are kept open when the system is in operation and will automatically shut by taking away the power supply. This happens when there is a problem with a unit or a ...
