PILOT VALVE (CONTROL LEVER)
3K2AQ00
When the lever (3) is kept at a certain position:
When the pressure in the output port A increases to a lev-
el equivalent to the force of the spring (6) set by the incli-
nation of the lever (3), the hydraulic pressure is balanced
with the spring force. When the pressure in the output
port A becomes higher than the set spring force, the out-
put port A is disconnected from the input port P and then
becomes connected to the tank port T. When the pres-
sure in the output port A drops below than the set spring
force, the output port A becomes connected to the input
port P and it is then disconnected from the tank port T.
The secondary pressure is thus always kept constant.
