Description
Four-Circuit Protection Valve for Kinglong Bus 3529-00063
This four-circuit protection valve (Model 3529-00063) is a critical air brake system component specifically engineered for Kinglong buses. As a central hub in the bus air brake system, this five-way valve divides the vehicle's air circuit into four interconnected yet independent circuits, providing essential shunting and protection functions.
Core Function & Safety Benefits
The primary function of this protection valve is to ensure that when one circuit fails due to air leakage or breakage, the remaining three circuits continue to operate normally. This critical safety feature prevents complete air brake system failure and directly enhances the driving safety of Kinglong buses.
Key Features & Advantages
  • Fixed model 3529-00063 designed specifically for Kinglong buses
  • Diaphragm-type internal structure for reliable performance
  • Superior airtightness and easy installation
  • Eliminates common issues like air leakage and uneven pressure distribution
  • Ideal for fleet maintenance and wholesale applications
Construction & Technical Design
Manufactured to strict production standards using precision technology, this valve features a robust construction with high-strength cast iron shell, wear-resistant diaphragm, precision valves, transmission ring, push plate, and pressure regulating spring. The corrosion-resistant shell ensures excellent pressure resistance and durability, while the high-elasticity rubber diaphragm provides sensitive pressure response and reliable sealing.
The valve configuration includes one air inlet and four air outlets connected to: front axle braking system, middle and rear axle braking system, parking braking system, and auxiliary braking system - enabling independent protection for each circuit.
Performance & Quality Assurance
During circuit failure, the valve maintains air pressure in remaining circuits at approximately 6.5 bar to ensure normal braking performance. Each unit undergoes rigorous quality inspections including air tightness tests, pressure regulation tests, and durability tests to guarantee stable performance, low failure rates, and full compliance with Kinglong OEM technical standards.
Installation & Compatibility
The standardized size and OEM-compatible design ensure perfect integration with various Kinglong bus models, allowing direct replacement without modifications. Installation involves aligning the valve body with the mounting bracket, securing with high-strength bolts, connecting air inlet/outlet pipelines according to markings, and testing pressure distribution and circuit protection performance.
