2. Plug valve - Wikipedia

   en.wikipedia.org/wiki/Plug_valve

   Slightly conically tapered metal (often brass) plug valves are often used as simple shut-off valves in household natural gas lines. It is also possible for a plug valve to have more than two ports. In a 3-way plug valve, flow from one port could be directed to either the second or third port.

3. Shutdown valve - Wikipedia

   en.wikipedia.org/wiki/Shutdown_valve

   A shutdown valve (also referred to as SDV or emergency shutdown valve, ESV, ESD, or ESDV; or safety shutoff valve) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to people, equipment or the environment.

4. Tap (valve) - Wikipedia

   Cone valves or ball valves are another alternative. These are commonly found as the service shut-off valves in more-expensive water systems and usually found in gas taps (and, incidentally, the cask beer taps referred to above). They can be identified by their range of motion—only 90°—between fully open and closed.

5. Isolation valve - Wikipedia

   en.wikipedia.org/wiki/Isolation_valve

   Isolation valves must effectively stop the passage of fluids. [4] Gate valves, ball valves and plug valves are generally considered to provide tight and effective shut-off. Globe valves and Butterfly valves may not be tight shut-off due to wear on the plug or the seat, or due to their design, and may not be appropriate to provide effective ...

6. Surface-supplied diving equipment - Wikipedia

   en.wikipedia.org/wiki/Surface-supplied_diving...

   Lightweight demand helmets are rigid structures which fully enclose the head of the diver and supply breathing gas "on demand". The flow of gas from the supply line is activated by inhalation reducing the pressure in the helmet to slightly below ambient, and a diaphragm in the demand valve senses this pressure difference and moves a lever to open the valve to allow breathing gas to flow into ...
