A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessa… WebValve Events. Valve Events may be defined as the four defining points in the cylinder power cycle – viz: Admission when the port opens allowing “live” (high pressure) steam from the steam chest to be admitted into the cylinder;; Cut-off when the valve closes the port, cutting off the steam supply to the cylinder;; Release when the valve opens the port allowing the …
