Functions and operation by valve
Pressurized oil (P1) and (P2) discharged from
q
the two pumps merge at ports (E) and (F), and
flow to the control valve which requires the oil.

q
LS spool (3) is also OFF, LS spool (3) is
pressed to the right by spring (4). As a result,
ports (A) and (B) are interconnected and ports
(B) and (C) are interconnected.
q The LS pressures transmitted from respective
control valve spools through LS circuits (5), (6),
(7), and (8) are transmitted to all the pressure
compensation valves.
