Cyclopedia of locomotive engineering, with examination questions and answers; a practical manual on the construction care and management of modern locomotives . lever in center of quadrant. Starting valveS closed as in Fig 1460 This places both valves A andB in central position, covering all ports on side to betested. | By opening throttle, steam is admitted to the high- Ipressure steam chest E, as shown in shade. If steam |now flows from either cylinder cock, H or I, the high-pressure valve A is blowing. Testing Low-Pressure Valve. Engine on top quarter*Reverse lever on center, as in Fig. 140. Startingvalve S open, as in Fig. 145. Remove by-pass valve M in Fig. 145, but replacevalve-cap, which is not shown, as it is bolted to underside of starting valve. This allows steam to flowthrough by-pass from high-pressure steam chest E, jthrough starting valve ports N and O, and past exhaustedges X and Y of high-pressure valve A, into low-jpressure steam chest P., If steam now blows from both low-pressure cylindecocks K and L, the low-pressure valve B is leaking.
