We look forward to working with youHydraulic Brake ValvesThe 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 fl 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 fl uid system.Unless specifi ed, all valves in this catalog are used with mineral base hydraulic oil. Consult MICO when using other fl 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 proper online Application Data Sheet (80-460-042 or 80-460-046) at www.mico.com. The MICO Applications Department will analyze your specifi cations and recommend a hydraulic brake valve most suitable to the requirements.For more information about MICO® Accumulator Charging Valves and MICO® Integrated Modulating Valves/Charging Valves see catalog 84-463-001.4 MICO, Inc.

Dimensional illustrations in this catalog are shown in the standard orientation.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 fl atter slope for the fi 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.6 MICO, Inc. Form No. 84-466-001 Online Revision 2012-11-06Single Modulating ValvesDESCRIPTIONThese 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.FEATURES ? Compact size for use in restricted space ?

Form No. 84-466-001 Online Revision 2012-11-06DESCRIPTIONThese 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 ? Compact size for use in restricted space ? Provides independent braking to front and rear brake systems from one valve ? Oil immersed spring cavity protects return springs from outside contaminants ?

Form No. 84-466-001 Online Revision 2012-11-06DESCRIPTIONThese 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 ?

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 effi ciently provide required fl uid volume. These relay valves use pilot pressure from a remote brake valve to control modulated brake pressure.FEATURES ? Compact size for use in restricted spaces ?

Form No. 84-466-001 Online Revision 2012-11-06DESCRIPTIONThe 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.

Form No. 84-466-001 Online Revision 2012-11-06PRINCIPLES OF OPERATIONThe 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 suffi cient pressure is reached in the system. FEATURES ? Added safety for vehicle and operator ? Controls on/off function of spring apply/hydraulic release parking brake ? Detents in the brake-release and brake-apply positions ? Automatically applies parking brake in the event of pressure loss ? Helps prevent dragging and excessive parking brake wear ? Alternate version incorporates a secondary means of manual actuation which is typically linked to a panic bar actuator in underground mining applicationsTypical Circuit SchematicPark Brake Valveswith Auto ApplyMICO, Inc.

Form No. 84-466-001 Online Revision 2012-11-06PRINCIPLES OF OPERATIONThe MICO® Dual Power Brake Valve for Steering Assist is a closed center design used for modulating output pressures up to 137.9 bar (2000 PSI). This valve in conjunction with properly sized accumulators, provides normal and emergency power-off braking.This unique integrated design can easily adapt to many dual pedal systems to provide steering assist power braking with one pedal applied or full power braking with both pedals applied giving equally balanced brake pres-sures.The MICO® Dual Power Brake Valve for Steering Assist can be adapted into a variety of hydraulic systems.FEATURES ? Compact integrated design for use in restricted space ? Power off braking through limited stored energy in the accumulators ? Spool type construction provides smooth modulation at low pressures ? Direct acting spool provides a pedal feel accurately representing brake pressure ? One brake light switch port for monitoring individual or balanced brake pressure ? Auxiliary left and right side accumulator pressure switch ports ?
