The Pulse Width Modulated (PWM) Valve is used on the
Multi Pro 5700–D to control gear pump flow to the spray
pump hydraulic motor. Electrical current to the PWM
Valve solenoid coil affects the internal spool setting of
the Valve and thus the hydraulic flow to the spray pump
motor. Component parts for the PWM Valve are not
available.
IMPORTANT: Correct operation of the PWM Valve
depends on precise assembly and adjustment. No
disassembly or adjustment of the PWM Valve is rec-
ommended.
For information on PWM Valve solenoid testing, see
Pulse Width Modulated (PWM) Valve Solenoid in the
Component Testing section of Chapter 5 – Electrical
System.
