Pilot Control Valve (Work Lever / Joystick)
GENERAL DESCRIPTION
THEORY OF OPERATION
Structure
The remote control valve contains four push rods, spring holders, spools and return springs, which are
located in the valve casing. The valve works as a pressure reduction valve.
The housing has six ports, which include input port P, tank port T, and four secondary pressure ports.
The electric horn switch is installed in the valve handle. Gear pump pressure is used for operating control
spools.
Function
1.
Neutral Mode
When the lever is in neutral mode, the spool is thrust upward by return spring, and the force of
balancing spring, which determines the secondary discharge pressure, is not transmitted to the
spool. The input port is closed and the pressure of the output port is the same as the pressure of the
tank port T.
2.
Control Mode
When push rod is pushed, the balance spring begins to compress, and spring force is conveyed to
the spool. Ports P and T are then connected together and the pilot pressure is conveyed to the area.
Output pressure works on the bottom of the spool, thrusting the spool upward until it is balanced with
the power of the balance spring. The secondary pressure (output pressure), therefore, changes in
proportion to the compression force of the balance spring.
