2. Valve Turners - Wikipedia

   en.wikipedia.org/wiki/Valve_turners

   On October 11, five members of Climate Direct Action simultaneously turned emergency shut-off valves in four American states. This was the largest valve-turning action to date, temporarily disabling pipelines providing about 15% of America's daily oil consumption. [3] Michael Foster turned a valve in North Dakota near the Canadian border.

3. Shut-off nozzle - Wikipedia

   en.wikipedia.org/wiki/Shut-off_nozzle

   Bolt Shut-off Nozzle type BHP - pneumatic or hydraulic actuation. A shut-off bolt, positioned perpendicular to the melt channel moves up and down according to actuation, and thus shuts off/opens the melt flow. This nozzle type has a single melt channel. It therefore does not require rerouting of the melt around the shut-off mechanism.

4. List of valves - Wikipedia

   en.wikipedia.org/wiki/List_of_valves

   Valves can be categorized into the following types, based on their operating mechanism: Ball valve, for on–off control without pressure drop. Ideal for quick shut-off, since a 90° turn completely shuts off, compared to multiple 360° turns for other manual valves; Butterfly valve, for on–off flow control in large diameter pipes

5. 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.

6. Partial stroke testing - Wikipedia

   en.wikipedia.org/wiki/Partial_stroke_testing

   Partial stroke testing (or PST) is a technique used in a control system to allow the user to test a percentage of the possible failure modes of a shut down valve without the need to physically close the valve. PST is used to assist in determining that the safety function will operate on demand.
