Quick Release Valve
Volvo

The quick release valve is a critical control device in the vehicle’s pneumatic system, enabling rapid exhaust of compressed air from brake lines or actuators to achieve prompt brake release or actuator retraction. In Volvo trucks, this valve is designed for fast, controlled dissipation of pressure, minimizing lag between pedal input and brake response. Its robust seals and corrosion-resistant body help maintain performance under infrequent maintenance cycles or extended operation in harsh environments. The unit is built to resist leakage even in high-vibration settings and includes mounting provisions compatible with standard brackets. For fleets seeking improved brake response and reduced dwell time in systems with multiple actuators, this valve delivers tangible gains in stopping efficiency and reliability.
