Steam Engine Valve Centered with Piston

| View Cart ⇗ | Info

“It is usual to put the engine on center before setting the valve. First put the engine in a position where the piston has nearly completed the outward stroke, and make a mark M on the guide opposite the corner of the crosshead or at some convenient place.” —Derr, 1911
