REMOTE CONTROL VALVES
HYDRAULIC SYSTEMS INTRODUCTION
Two different types of hydraulic remote control valve
systems are used.
Standard Flow System
The standard flow system consists of a single axial
piston pump, 1, which supplies fluid to a hydraulic
steering flow divider and remote control valve
assembly. The pump is rated at 117 L/min (31 GPM).

HydraFlow Plus System
The HydraFlow Plus system consists of two axial
piston pumps which supply fluid to the high pressure
hydraulic system. The system has a total flow rating
of 208 L/min (55 GPM). The remote control valve
assembly is divided internally into two separate
systems.
The upper pump, 1, is the same pump used on the
standard hydraulic system. It is rated at 117 L/min (31
GPM) and supplies fluid to the hydraulic steering flow
divider and to remote valve sections I and II.
The lower axial piston pump, 2, is rated at 91 L/min
(24 GPM) and supplies fluid to the three-point hitch
valve and remote valve sections III and IV.
The HydraFlow Plus system offers increased flow
and dual system capability which will allow for more
efficient operation of large individual hydraulic loads
such as dual orbit motors and remote cylinders.
One side of the system can be used for the operation
of a high flow/low pressure requirement, and the
other side of the system can be used for a low
flow/high pressure requirement such as found on
certain hydraulic driven air seeders.

WARNING
Hydraulic oil escaping under pressure can
penetrate the skin causing serious injury.
•
Use a piece of cardboard or paper, instead of
your hand, to search for leaks.
• Stop the engine and relieve pressure before
connecting or disconnecting lines.
• Tighten all connections before starting the
engine or pressurizing lines.
If any fluid is injected into the skin, obtain
medical attention immediately or gangrene may
result.
