Hydraulic Brake Valves
The same dependability, safety and performance that
goes into every MICO Braking System Product also
goes into our versatile, high-performance Brake Valves
and Brake Valve Components. This is an important
consideration when you select a source of supply for
your uid power needs.
The MICO® Brake Valves presented in this catalog
are designed for vehicles that are equipped with other
hydraulic power devices in either open center, closed
center or load sensing hydraulic systems. This design
feature eliminates the need for a separate power brake
unit or separate hydraulic uid system.
Unless specied, all valves in this catalog are used with
mineral base hydraulic oil. Consult MICO when using
other uids. Dimensional drawings shown may vary
slightly between similar units and are to be used for
reference purposes only.
For more information regarding brake system design
see Technical papers 80-950-073, 80-950-074,
80-950-098, and 80-950-102 at www.mico.com.
Complete the appropriate Application Data Sheet online,
www.mico.com. The MICO Applications Department will
analyze your specications and based on your input
recommend a hydraulic brake valve suitable for your
requirements.

Explanation:
Linear brake pressure curve is a straight line
from the end of dead band (start of pressure
rise) to the ultimate pressure setting.
Staged brake pressure rise has a atter
slope for the rst part of the curve and then
transitions to a steeper slope to achieve
the ultimate pressure setting. Staged brake
pressure rise can be favorable in applications
where less aggressive braking is desired in
early input actuation.

Single Modulating Valves
DESCRIPTION
These MICO® Single Modulating Valves are a closed
center spool design. They provide a modulated output
pressure of up to 206.8 bar (3000 PSI) and a maximum
input pressure of 206.8 bar (3000 PSI). Standard brake
pressure settings are in increments of 3.5 bar (50 PSI).
When used with a properly sized accumulator and a
MICO® Accumulator Charging Valve, these valves
provide normal and emergency power-off braking in a
variety of open-center, closed-center, and load sensing
hydraulic systems. For detailed information about
principles of operation contact MICO.
Available as valve only, push rod actuated, lever
actuated, and pedal actuated. These valves can also
be designed with options such as built-in switches,
potentiometers, etc.

DESCRIPTION
These MICO® Tandem Modulating Valves are a closed
center spool design, providing isolated pressure outputs
for front and rear brakes. In the event of failure in either
half of the brake system, the other portion of the brake
valve will continue to function. They provide a modu-
lated output pressure of up to 206.8 bar (3000 PSI) and
a maximum input pressure of 206.8 bar (3000 PSI).
Standard brake pressure settings are in increments of
3.5 bar (50 PSI).
When used with properly sized accumulators and a
MICO® Accumulator Charging Valve, these valves
provide normal and emergency power-off braking in a
variety of open-center, closed-center, and load sensing
hydraulic systems. For detailed information about prin-
ciples of operation contact MICO.
Models are available as valve only, push rod actuated,
lever actuated, and pedal actuated. These valves can
also be designed with options such as built-in switches,
potentiometers, etc.
FEATURES
z Compact size for use in restricted space
z Provides independent braking to front and rear brake
systems from one valve
z Oil immersed spring cavity protects return springs
from outside contaminants
z Spool design provides smooth modulation at all
pressures
z Provides "pedal feel" proportional to brake system
pressure
z Tank ports communicated internally allow for one or
two return lines to tank

DESCRIPTION
The MICO® Tandem Modulating Valves with Pilot func-
tion is the same as a mechanically actuated tandem
modulating valve. The pilot apply port provides an
additional method for on/off brake application through
a hydraulic signal from a remote location. Full brake
pressure from the pilot apply feature is provided when
given the pressure shown in the specications chart.
Pilot apply is for temporary full apply of the service
brakes and not intended for use as a park brake or
extended braking.
For detailed information about principles of operation
contact MICO.
Available as valve only, push rod actuated, lever
actuated, and pedal actuated. These valves can also
be designed with options such as built-in switches,
potentiometers, etc.
FEATURES
z Compact size for use in restricted space
z Provides independent braking to front and rear brake
systems from one valve
z Oil immersed spring cavity protects return springs
from outside contaminants
z Spool design provides smooth modulation at all
pressures
z Tank ports communicated internally allow for one or
two return lines to tank
z Pilot apply function is provided with zero leakage,
low volume actuation
z Pilot apply pressure from a remote location provides
a hydraulic signal for on/off brake system pressure

DESCRIPTION
The MICO® Tandem Modulating Valves with Pilot func-
tion is the same as a mechanically actuated tandem
modulating valve with an added hydraulic pilot apply
port. The pilot apply provides an additional method for
direct acting, proportional brake application at a one-
to-one ratio through a hydraulic signal from a remote
location. Pilot apply gives the operator a "pedal feel"
proportional to brake system pressure.
For detailed information about principles of operation
contact MICO.
Available as valve only, push rod actuated, lever
actuated, and pedal actuated. These valves can also
be designed with options such as built-in switches,
potentiometers, etc.
FEATURES
z Compact size for use in restricted space
z Provides independent braking to front and rear brake
systems from one valve
z Oil immersed spring cavity protects return springs
from outside contaminants
z Spool design provides smooth modulation at all
pressures
z Tank ports communicated internally allow for one or
two return lines to tank
z Pilot apply pressure is controlled by a full power
valve such as a MICO
®
Single Modulating Valve
z Pilot apply pressure is a one-to-one ratio to brake
system pressure

PRINCIPLES OF OPERATION
These MICO® Single Modulating Valves with Pilot are a
combination of a single modulating valve and a hydrau-
lic pilot section. The pilot apply provides an additional
method for brake application through a hydraulic signal
from a remote location. Two independent valves share
a single pedal. They provide a modulated output pres-
sure of up to 206.8 bar (3000 PSI) and a maximum input
pressure of 206.8 bar (3000 PSI). Standard brake pres-
sure settings are in increments of 3.5 bar (50 PSI).
The poppet design modulating valves are capable of
higher ow capacity than the spool design modulating
valves. The poppet design also allows for virtually zero
internal leakage compared to the spool design. For
detailed information about principles of operation contact

Available as valve only, push rod actuated, and pedal
actuated. These valves can also be designed with
options such as built-in switches, potentiometers, etc.

DESCRIPTION
These MICO® Reverse Modulating Valves can be used
in negative braking systems to actuate a spring apply/
hydraulic release service brake. The term “reverse
modulating” is used because pressure is decreased to
actuate the brake from a preset pressure that keeps the
brake fully released. The preset pressure is regulated to
a level above the full release pressure of the brake and
must be maintained to assure that brake drag does not
occur.
To actuate the spring apply/hydraulic release brake,
apply the brake pedal and hydraulic pressure in the
brake system is reduced causing the springs to apply
the brake. Brake pedal position and force is proportional
to the brake system pressure and provides the feedback
necessary for good braking control.
Models are available with a latched pedal design for use
in parking and/or dynamic braking.
FEATURES
z Compact size for use in restricted spaces
z Oil immersed spring cavity protects return springs
from outside contaminants
z Spool design provides smooth modulation at all
pressures

DESCRIPTION
MICO® Relay Valves are a closed center design used for
modulating output pressures up to 207 bar (3000 PSI).
They can be adapted into a variety of hydraulic systems
and are used in circuits where the brake control valve is
too far from the brake to efciently provide required uid
volume. These relay valves use pilot pressure from a
remote brake valve to control modulated brake pressure.
FEATURES
z Compact size for use in restricted spaces
z Spool design provides smooth modulation at all
pressures
z Power-off braking through limited stored energy in
the accumulator(s)

DESCRIPTION
The MICO® Hystat Brake Valve was developed to
destroke a hydrostatic transmission and then apply the
vehicle brakes. This function is normally described as
inching. When the valve is released, the brakes release
and the hydrostatic transmission re-engages. This valve
is application specic and must be carefully sized, con-
tact MICO.

PRINCIPLES OF OPERATION
The MICO® Park Brake Valve with Auto Apply provides
added safety for vehicle and operator by controlling the
actuation of the spring apply, hydraulic release park
brake. Actuation is controlled either manually or by the
emergency auto apply section of the valve. Manual con-
trol can be performed with a cable-lever arrangement or
a hand grip knob for push-release/pull-apply operation.
The auto apply section of the park brake valve senses
accumulator and brake pressure and at a predetermined
declining pressure will automatically apply the brake
100%. With the brake applied, the control shaft is au-
tomatically moved to the apply position. A low pressure
warning switch should also be installed in the system to
alert the operator before an emergency actuation.
Before moving the vehicle, system accumulator pres-
sure must rise above the auto apply pressure setting.
The control shaft must then be moved to the released
position. The control shaft cannot physically be moved
to the release position until sufcient pressure is
reached in the system.
FEATURES
z Added safety for vehicle and operator
z Controls on/off function of spring apply/hydraulic
release parking brake
z Detents in the brake-release and brake-apply
positions
z Automatically applies parking brake in the event of
pressure loss
z Helps prevent dragging and excessive parking
brake wear
z Alternate version incorporates a secondary means of
manual actuation which is typically linked to a panic
bar actuator in underground mining applications
