SPEED VALVE ADJUSTMENT

REGENERATIVE VALVE DESIGN

The design of the regenerative flow valve used in Stanley LaBounty Mobile Proceesros consists of a pilot

valve mounted onto a spool valve. The pilot valve is used for regulating the movement of the spool valve

in shifting the valve into and out of regenerative mode. See Figure 5-46. The only component that is in the

working flow path of the fluid to the proceesor cylinder is the valve spool. The valve spool is of similar con-

struction to that of the excavator’s main control valve spool. Therefore, it is considerably larger than the com-

ponents found in a typical cartridge type regenerative valve.

OPERATING CHARACTERISTICS

The function of the regenerative valve is to provide for rapid advance of the proceesor hydraulic cylinder dur-

ing the closing phase of the proceesor cycle. The valve accomplishes this function by shifting a valve spool

to open the rod side of the cylinder to the bore side of the cylinder, thus allowing the fluid in the rod side to

fill the bore side when the cylinder is extending. This function only occurs when the cylinder is advancing in

a “low load” condition, which occurs as the proceesor jaw is closing down onto the material that it is about

to be cut. As the proceesor enters the cutting phase, the operating pressure requirements increase. The

pilot valve portion of the regenerative valve, which in turn causes the valve spool to shift out of regenerative

mode, senses the increased pressure. During this phase, the rod-side fluid is directed to the work line and

back to the base machine’s reservoir (low pressure). Meanwhile, only the flow from the excavator’s control

valve is directed to the bore side of the cylinder, allowing it to reach full system operating pressure. This al-

lows the proceesor to cut by utilizing the full power of the excavator with resistance coming only from the

material being cut by the proceesor.

TROUBLESHOOTING

There are two operating conditions that affect the

performance of the speed valve and will require

some troubleshooting by an equipment mechanic or

service representative. These conditions are:

a. The speed valve does not seem to shift out of

regenerative mode at the appropriate time resulting

in the processor appearing to lose cutting power, or

b. The speed valve does not appear to shift into

regenerative mode resulting in a slow closing move-

ment of the proceesor jaw. Both of these condi-

tions can be remedied by following the speed valve

adjustment procedure discussed on the following

pages.

If making the appropriate adjustments does not

remedy the above conditions, refer to page 6-11 of

this manual for further troubleshooting guidelines. If

further difﬁculties are encountered, the speed valve

may require replacement of the hydraulic seals.

Seal kits are available from the Stanley LaBounty

Customer Service Department. Processor serial

number will be required when ordering.
