   Watt had fitted two conical valves to the upper steam passage to the steam cylinder and two to the lower passage. This is well illustrated in the text by Lardner (1840). [9] This arrangement of two such valves per steam passage was described as the 'double-beat', 'balanced' or 'equilibrium' poppet valve by various authors (see e.g. Clark 1891 ...

   en.wikipedia.org/wiki/Gate_valve

   Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...

   This entails controlling the admission and exhaust of steam to and from the cylinders with a valve linked to the motion of the piston. [3] For timing and dimensioning of slide or piston valves where the valve opens and closes the steam and exhaust ports, a consideration of the "lap" and "lead" is required.

   Produces the motion for the locomotive from expansion of the steam. Driven backward and forward within the cylinder by steam delivered alternately, in front and behind, by the valve.
