The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open. Plug valves are simple and often economical. When the plug is conically tapered, the stem/handle is typically attached to the larger diameter end of the plug. Plug valves usually do not ...
This article has only considered inside-admission piston valves until now, but outside-admission valves (slide valves and some piston valves) can use Walschaerts valve gear. If the valves have outside admission the radius bar connects to the combination lever below the valve stem rather than above and the orientation of the eccentric crank is ...
Eccentric reducers exhibit a unique design with one side having a larger diameter and the other side being smaller and offset from the centerline. This offset configuration enables the eccentric reducer to maintain a consistent fluid level within the piping system, preventing air or gas accumulation.
Soo Line 346 in 1961, showing the Kinkan-Ripken arm on the connecting rod at the right hand edge of the picture Kingan-Ripken valve gear. This is a Walschaerts-type gear in which the combination lever is linked to an arm on the connecting rod, near its small end, instead of to the crosshead.

The valve gear gab of Calvert's beam engine, disengaged. The hooked rod from the right is driven by the eccentric. When engaged, it rocks the valve arbor, the square shaft, back and forth. Bellcranks behind the shaft work the valves via the vertical pullrods. Gab valve gear was an early form of valve gear used on steam engines. Its simplest ...
Unlike the Walschaerts and Baker systems, the Southern valve gear dispensed with the combination lever which transmitted some of the crosshead motion to the valves. As with those systems it used a return crank on a driver (instead of the eccentrics used by the Stephenson valve gear). The return crank attached to the eccentric rod, which hung ...
