Genuine Wabco parts – Pressure Limiting Valve

Part number: 4750090080

Products description & Function:

The function of Wabco pressure limiting valve is to regulate and control the pressure in the hydraulic system to ensure the safe operation of the system.

Wabco pressure limiting valve is an important hydraulic component, mainly used in pneumatic and hydraulic systems of trucks, buses and other vehicles. Its main function is to limit the maximum pressure of the hydraulic system to prevent excessive system pressure from causing equipment damage or safety accidents. By adjusting the setting of the pressure limiting valve, it can ensure that the system can maintain a stable pressure under various working conditions, thereby protecting the safety and reliability of the vehicle braking system. In addition, the adjustment of Wabco pressure limiting valve can also optimize system performance, improve energy efficiency, and reduce unnecessary energy consumption.

The Components:

Wabco’s product features in the commercial vehicle field, pressure limiting valves usually contain the following key components:

1. Valve body: This is the main part of the pressure limiting valve, usually made of metal, with sufficient strength and corrosion resistance to withstand the working pressure of the system and the influence of the external environment. The valve body is designed with a flow channel inside to guide the flow of the fluid. ‌

2. Valve core: The valve core is the active part in the pressure limiting valve. It moves in the valve body according to the changes in system pressure to control the flow of fluid. The design of the valve core usually includes a sealing surface and a guide part to ensure the sealing and stability of the valve. ‌

3. Spring: The spring is an important component in the pressure limiting valve. It provides the necessary preload to keep the valve core closed when the set pressure is not reached. When the system pressure exceeds the set value, the spring is compressed, allowing the valve core to move and release the pressure. ‌

4. Adjustment mechanism (if applicable): Some pressure limiting valves may be equipped with an adjustment mechanism to allow the user to adjust the set pressure of the valve as needed. This is usually achieved by rotating or adjusting a certain component to change the preload of the spring. ‌

5. Seal: Seals such as O-rings, gaskets, etc. are used to ensure the sealing of the valve and prevent fluid leakage. These seals are usually made of oil-resistant and wear-resistant materials to extend the service life of the valve. ‌

6. Connectors: The pressure limiting valve is usually connected to the system pipeline through threads, flanges or other connection methods. The quality and sealing of the connectors are crucial to the overall performance of the system. ‌
