Each of the ten colossal machines, such as those used in large-scale industrial applications or fictional depictions, typically featured a varying number of valves depending on their specific design and purpose. Generally, these machines could incorporate anywhere from dozens to hundreds of valves to manage fluid flow, pressure, and various operational functions. The exact number would depend on the complexity and requirements of the machine's engineering. For precise details, one would need to refer to the specifications of each individual machine.
they have two - four valves
The Colossus was built using thermionic valves, thyratrons, relays and stepping switches.The Colossus Mark 1 used about 1600 valves and the Colossus Mark 2 used about 2400 valves. After the Colossus Mark 2 was in production and use the single Colossus Mark 1 was briefly shutdown and upgraded to a Colossus Mark 2. Five of the ten Colossus machines also had a device called the "gadget" that aided in a process called "rectangling", the number of additional valves added to each of these enhanced Colossus Mark 2 machines is unknown.

60 (5 valves for each of the 12 cylinders. Three of the valves on each cylinder are for intake and two are for exhaust.)
there are 3 valves, and 4 slides (one for each valve and a tuning slide)
4 cylinders x 5 valves (each cylinder) = 20 valves total
That would depend on how many valves each cylinder has and the location of the camshaft.
This engine (allowing it is an automotive engine) is a four valve per cylinder engine.
On a 1999 Ford Taurus : If you have the 3.0 " Vulcan " V6 engine ( which is an Over Head Valve / pushrod design engine ) there are ( a total of 12 valves , 2 valves for each engine cylinder ) If you have the 3.0 " Duratec " V6 engine ( which is a Dual Over Head Cam design engine ) there are ( a total of 24 valves , 4 valves for each engine cylinder )
