Air Brake Protection Valve

9347020400 Air Brake Protection Valve belongs to FOUR CIRCUIT PROTECTION VALVE.

Core Functions

·Distributes compressed air to four independent braking circuits

·Prioritizes air supply to the braking system

·Maintains normal operating pressure in other circuits if a single circuit fails

Operating Logic

·Activates output circuits sequentially according to preset pressure thresholds

·Monitors the pressure status of each circuit in real time

·Automatically isolates leaking circuits while maintaining system redundancy

Technical Highlights

·Diaphragm-free design eliminates aging risks

·Tapered sealing structure achieves zero leakage maintenance

Typical Applications

·Commercial vehicle braking systems compliant with regulatory requirements

·Multi-circuit air-consuming equipment such as concrete mixer trucks

·Safety systems for hazardous goods transport vehicles

Maintenance Requirements:

·Quarterly inspection of circuit isolation performance

·Regular drainage to prevent valve cavity icing

·Recommended to use specialized tools for opening pressure calibration

9347020400 Air Brake Protection Valve belongs to AIR HANDLING SYSTEM.
