Introduction
General description
The CVG (Control Valve Group) is a compact load-
sensing valve assembly consisting of multiple direction-
al valve sections. Each control section has its own com-
pensator, so that speed control of multiple sections is
achieved, regardless of changes in pressure. The com-
pensator limits the maximum flow of control section and
it can be adjusted. Each control section has pressure
limiting valves in work ports. If load exceeds the setting,
the control section starts to reduce flow. The control sec-
tion keeps flow steady with different main spool opening
if pressure changes.
The design of the CVG is modular. There are three nom-
inal sizes of control sections available: CVG30, CVG50
and CVG60. Different sizes can be fitted together with
adapters. The nominal size determines the port sizes
and compensators flow range. Specific flow range is se-
lected by a main spool in each control section. The in-
let section has an option for a main pressure relief valve
and a pilot oil reducing valve for electrically controlled
CVG. The outlet section has also ports P and T to en-
sure full flow for control sections.
The main spool of control section can be operated pro-
portionally with hydraulic remote or electrically in an
open loop and also in a closed loop depending on op-
tion.
Applications
A CVG can be used to control wide range of machines
like cranes, large mobile vehicles, lifting equipment, drill-
ing equipment and stationary applications. High flows
can be accurately controlled with low pressure drop and
low hysteresis.
Benefits
Excellent machine controllability – individual pres-
sure compensation in each work section delivers pre-
dictable metering with single and multi-function oper-
ation, regardless of changes in pressure or input flow.
The maximum work pressure can be limited individually
in each work port. This enhances machine control and
improves productivity. The CVG has excellent linearity,
repeatability and low hysteresis.
Flexible design – the modular CVG design enables the
machine designer to add or remove content to achieve
the machine requirements. Different nominal sizes, sev-
eral spools and a wide range of spool control options
provide wide range of possibilities where to build cus-
tomized assembly to meet the requirements.
Wide flow range – the CVG single control sections can
handle flow starting from 50LPM in nominal size CVG30
ending up to 2000 LPM in CVG60. Inlet and outlet can
handle pump input up to 10 000LPM in CVG60.
Energy-efficient – high level controllability and efficien-
cy can be achieved by choosing the right spool size from
different nominal sizes. CVG can handle load pressure
up to 420 bar. With right system design this gives pos-
sibility to reduce oil flow and still have same power sup-
plied through the valve.
Factory tested – every CVG valve assemblies are test-
ed and adjusted before sending to the customer. This
reduces start up time and reduces risk of system fail-
ure. Customer individual features can be fully tested be-
fore start up.
Ease of service – the components of CVG are easily
changed without removing CVG from the system. Com-
pensator, pressure limiting valves and load-sensing
check valve are located on the top of each controls sec-
tion making it a service friendly design. Spare parts are
available worldwide from Parker.

Introduction
Operation
Speed and direction movements of actuators are pro-
portionally controlled by spring centered main spools.
The pilot pressure moves the main spool against spring
force. In the electric version pilot pressure is adjusted by
electro-proportional 3-way pressure reduction valves. In
the hydraulic version the pilot pressure is adjusted by an
external control valve. The pilot oil flow to electro-pro-
portional pilot valves is supplied either internally or ex-
ternally. The internal signal is taken from port P through
a pressure reducing valve in the inlet section.
The pressure difference over main spool is kept constant
by a 2-way pressure compensator. Flow (and speed of
actuator) with certain opening of the main spool is con-
stant independent of load variations. Pressure compen-
sators are equipped with adjustable springs. The spring
force sets also a limit for maximum flow (speed of actua-
tor). Maximum feeding pressures in work ports A and B
are adjusted separately. When pressure exceeds setting
of the pilot valve, the pressure compensator starts to act
like a pressure reducing valve.
The CVG is a load sensing valve group. Every main
spool is equipped with LS signal channels. The highest
load pressure in the system is always connected to the
LS port in the inlet section. This signal can be used to
control a variable displacement pump. A CVG can be
used with fixed displacement pumps when the inlet sec-
tion is equipped with a 3-way pressure compensator.
When the system pressure exceeds the setting of the
pilot valve of the 3-way compensator, it starts to act like
a pressure relief valve.
In the open loop version, the position of the main spool
follows electric control signal coming from the amplifi-
er card. The main spool can be equipped with a position
sensor to read the movement of the main spool. In close
loop control with electro-proportional control version,
the position signal is sent to the amplifier card that com-
pares position signal to command signal and corrects
the control signal to solenoids accordingly. When hav-
ing close loop control option in CVG, the electro propor-
tional control end of spool is replaced with the close loop
control valve end. It has onboard electronics to compare
spool position to command signal and needs only power
supply and command signal for the main spool position.

The pressure difference over compensator is measured
when compensator spool is forced fully open. Pressure
is measured from ports MP and M1. Total pressure loss
over control section is sum of compensator spool pres-
