The Casablanca-class escort carrier, the most prolific aircraft carrier design in history, used two 5-cylinder Skinner Unaflow engines, but these were not steeple compounds. A non-compound Skinner Uniflow remained in service until 2013 in the Great Lakes cement carrier SS St. Marys Challenger, installed when the vessel was re-powered in 1950 ...
Diagram of cylinder and piston valve. The valve is next opened by moving it to the right, allowing the clear space in the middle of the valve to align with the channel in the cylinder above it. Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive.
Uniflow steam engine, a steam engine with a long uniflow cylinder that receives inlet steam at each end (for a double-acting engine) and exhausts through ports at the centre. Uniflow diesel engine, a two-stroke diesel engine with inlet through piston-ported fixed ports in the lower part of the cylinder, and exhaust through valves in the ...
The valve gear, actuated by connection to the driving wheels, ensures that steam is delivered to the piston with precision. Types are slide valves, piston valves or poppet valves.

In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston ...

Inclined engines have an inclined cylinder. Undertype engines are distinguished by having a locomotive-style boiler over top of a horizontal engine. Stationary engines may be classified by secondary characteristics as well: High-speed engines are distinguished by fast-acting valves. Corliss engines are distinguished by special rotary valve gear.
