Air Pressure Limiter / Valve Unit Euro4
It ensures that downstream components receive air only within the safe, specified pressure range, preventing over-pressurization that could damage valves, brake chambers, and pneumatic accessories. Engineered with high-accuracy internal mechanisms and durable materials, the valve provides reliable pressure control under varying loads, temperatures, and driving conditions. Its Euro4 compatibility ensures optimal integration with modern emission-regulated braking systems.
By maintaining stable air pressure, the valve enhances braking safety, prolongs component life, and supports consistent system performance.
Key Features
- Precision pressure-regulating valve for Euro4 air-brake systems
- Prevents over-pressurization and protects brake components
- High-accuracy internal control mechanism
- Durable, corrosion-resistant construction
- Ensures stable pressure delivery for consistent braking performance
