Advantages Of Relay Valves

Shorten brake reaction time‌: The relay valve can quickly deliver compressed air in the air reservoir to the brake air chamber, thereby significantly shortening the brake reaction time and enhancing the braking effect‌.

 

Enhanced braking effect: The relay valve quickly transmits compressed air to enable the brake shoe or brake disc to quickly generate braking force, effectively reducing the vehicle speed.

 

‌Improve the sensitivity and reliability of the braking system‌: Compared with traditional braking methods, the relay valve reduces the braking response time and improves the sensitivity and reliability of braking‌.

 

‌Preventing overload of mechanical transmission components‌: The relay valve can prevent the driving and parking systems from operating at the same time, avoiding the overlap of forces in the combined spring brake cylinder and the spring brake chamber, thereby preventing the mechanical transmission components from overloading and causing the spring brake to fail. Rapid filling and exhaust of the cylinder.

 

Applicable to large vehicles: In the braking system of trailers or large trucks, the relay valve can effectively shorten the inflation and exhaust time of the pneumatic brake system during the pressurization and depressurization process, and improve the response speed of the system.

Applications Of Relay Valves In The Automotive Industry

 

Braking Systems

One of the most critical applications of relay valves in the automotive industry is in braking systems. In heavy-duty vehicles such as trucks, buses, and trailers, the braking system requires a significant amount of air pressure to operate effectively. Relay valves are used to amplify the small control signal from the brake pedal into a larger output signal, which then activates the brake chambers and applies the brakes. This allows for a more responsive and efficient braking system, reducing the stopping distance and improving overall safety.

 

Suspension Systems

Relay valves are also widely used in automotive suspension systems to control the height and stiffness of the vehicle. In modern vehicles, air suspension systems are becoming increasingly popular due to their ability to provide a smoother ride and better handling. Relay valves are used to regulate the flow of air into and out of the air springs, allowing for precise control of the suspension height and firmness.

 

Transmission Systems

In some automotive applications, relay valves are used in transmission systems to control the shifting of gears. In automatic transmissions, the transmission control module (TCM) sends signals to the relay valves to engage or disengage the clutches and bands, allowing for smooth and efficient gear changes.

 

Air Compressor Systems

Relay valves are also used in air compressor systems in vehicles to regulate the pressure and flow of compressed air. In heavy-duty vehicles, air compressors are used to supply compressed air to various systems, such as the braking system, suspension system, and air horns. Relay valves are used to control the operation of the air compressor, ensuring that the compressed air is delivered at the correct pressure and flow rate.

FAQ

Q: If accessories are urgently needed, can they be supplied quickly?

A: We have an emergency parts supply mechanism and will arrange shipment as soon as possible to meet your needs. Please consult customer service for specific time.

Q: How do you control product quality?

A: 1) Each production batch will have a task list and a flow list.
2) Each batch of products will go through the first inspection, random inspection and final inspection, three processes to control the quality.

Q: Can I get samples?

A: We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost. If we don't have the goods in stock, we can deal with a small batch first. If you feel that our products meet your requirements, then you can cooperate with us for large orders.

Q: How does the factory control product quality?

A: Our factory has a strict quality control system, and every link from raw material procurement to finished product delivery undergoes strict inspection.

Q: Does the factory accept visits?

A: Yes, we welcome customers to visit our factory, but please make an appointment in advance so that we can prepare for the reception.

Q: Are relay valves suitable for high temperatures?

A: At the same time, under high temperature conditions, the internal components of the relay valve may expand due to thermal expansion, causing the valve to stick or seal to fail. The impact of humidity on relay valves is mainly reflected in corrosion and moisture intrusion.

Q: What are the signs of a failing relay valve?

A: Some signs of a bad relay valve include brakes that are slow to engage, poor brake response, and uneven brake wear. Regular maintenance and inspection of the air brake system, including the relay valve, are crucial for the safety of the driver and others on the road.

Q: Where would a relay valve be located?

A: The longer the distance from the foot valve to the rear chambers, the more time it will take (known as brake lag) before the rear brakes apply. To correct this condition on a long wheel base vehicle, a RELAY VALVE is installed near the rear brake chambers.
