2. Ball valve - Wikipedia

   en.wikipedia.org/wiki/Ball_valve

   A full bore (sometimes full port) ball valve has an oversized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines that require pigging.

   Full port (or full bore) ball valves cause no problems because the inside diameter of the ball opening is the same as that of the pipe. Etymology

5. Block and bleed manifold - Wikipedia

   en.wikipedia.org/wiki/Block_and_bleed_manifold

   A Block and bleed manifold is a hydraulic manifold that combines one or more block/isolate valves, usually ball valves, and one or more bleed/vent valves, usually ball or needle valves, into one component for interface with other components (pressure measurement transmitters, gauges, switches, etc.) of a hydraulic system. The purpose of the ...

7. Pinch valve - Wikipedia

   en.wikipedia.org/wiki/Pinch_valve

   Pinch valves employ an elastic tubing (sleeve/hose) and a device that directly contacts the tubing (body). Forcing the tubing together creates a seal that is equivalent to the tubing's permeability. [1] Air-operated pinch valves consist of an elasticised reinforced rubber hose, a type of housing, and two socket end covers (or flanges).
