Functions and operation by valve
Travel junction valve
Function
When travel control lever is operated for straight-travel, travel junction valve does not receive the pilot
q
pressure (PST) from travel junction solenoid valve, thus right and left travel circuits interconnect each
other, and equal amount of oil is supplied to right and left travel motors to secure straight-travel ability.
q When travel control lever is operated for turning, travel junction valve receives the pilot pressure (PST)
from travel junction solenoid valve, thus right and left travel circuits are shut off each other, and indepen-
dent amount of oil is supplied to right and left travel motors to secure turning ability.
