Service Brake Valve

Service Brake Valve

Hydraulic brake valve with foot pedal for construction, agricultural and industrial handling & lifting equipment

Our service brake valve features a closed-center spool design and works in combination with accumulators and charging valves of matching specifications to ensure optimal performance. This provides service braking during normal operation and emergency braking in the event of hydraulic system power loss.

In its default free state, the brake port is connected to the tank port. When the pedal is pressed, the tank port is shut off from the brake port. Pressing further opens the pressure port to the brake port, and additional pedal force gradually increases brake pressure until it balances with the hydraulic feedback force. Releasing the pedal removes the applied force, and the valve automatically returns to its free state, which ensures the system is reset and ready for the next operation.

Features
  • Compact modular design for safe and reliable braking performance
  • Low internal leakage and fast response, improving overall system stability
  • Available in single- or dual-circuit designs, with multiple pedal and sensor configurations to suit different machine types

Yes. The service brake valve is designed with low internal leakage and fast response, providing excellent system stability, which aligns with the precise braking control required for truck applications. With an adjustable braking pressure range of 28–207 bar, it delivers the precision braking control needed for truck applications.

The valve enables smooth and controllable deceleration and stopping, ensuring safe and efficient operation even when handling large, heavy loads. So, it is absolutely suitable to be used for demanding heavy-duty operations.

Our service brake valve is available in single- and dual-circuit versions and supports multiple pedal and sensor configurations. Its modular design allows a small set of core components to meet different installation requirements, helping you significantly reduce spare parts management costs.
