PF2 will not have enough flow to operate if solenoid S1
and S2 are not activated or are inoperative.
The controlled flow going out of the PF2 valve is at port
M1. Excess flow is internally routed thru the block to
port T and is returned to tank.
The controlled flow going out of the PF2 speed control
exits the block at port “M1” and goes to the conveyor
motor to power the belt.
Internal bypass flow is routed back to tank at port “T”.
Refer to the “Electrical Systems” maintenance section in
this manual for information about servicing the electrical
connections to PF2.
The solenoid is a replaceable service part. The valve
body does not have any user serviceable parts. If the
valve is malfunctioning, it will need replacement.
An O-
ring kit is available for the valve.
