Brake Valves

 

Single Modulating Valve
Available feedback for electronic pedal angle control capability

When used with a properly sized accumulator and accumulator charging valve, the single modulating valves can provide normal and emergency power-off braking in a variety of open center, closed center and load sensing hydraulic systems.

 

Compact design is customizable to applications requirements

Spool design provides smooth modulation at specified pressures

Optional designs with built-in switches, and potentiometers

Eliminates the need for a separate power brake unit or separate hydraulic fluid system 

Tandem Modulating Valve
Superior Brake Performance

Operates similar to the single modulating valves, except two independent pressure outputs are provided. If either half of a dual brake system fails, the other half will continue to provide braking function.

 

Eliminates the need for separate power brake unit or separate hydraulic fluid system

Available as valve only, push-rod actuated, lever actuated and pedal actuated

Optional designs with built-in switches, and potentiometers 

Reverse Modulating Valve
Robust pedal design for demanding environment

Reverse modulating valves are used in negative brake systems for controlled actuation of spring apply/hydraulic release service brake. As the pedal is applied, pressure to the brake is reduced causing the brake to engage.

 

Precise control of modulated output pressure

Can be actuated by pull mechanism, or pedal

Optional lock lever available on pedal designs to hold at full release pressure
