HYDRAULIC CYLINDER ASSEMBLY
The hydraulic cylinder assembly (fig. 4-8) is
connected to the operation control assembly. The
hydraulic cylinder assembly is actuated by pressurized
hydraulic fluid to open and close the steam valve
assembly. When pressurized fluid is applied to port E,
the piston moves to the opposite end of the cylinder to
open the steam valve. The rate of movement of the
piston is faster at the beginning of the stroke, because of
