Applications

The accumulator charging valve is widely used in mining trucks, rubber-tired vehicles, wheel loaders, backhoe loaders, motor graders, tractors, forklifts, and telehandlers. It ensures that the accumulator consistently maintains an adequate supply of high-pressure hydraulic oil, providing critical backup energy for the braking system. This guarantees effective emergency braking even if the engine shuts down, the hydraulic pump fails, or the main system malfunctions.

In normal operating conditions, the valve delivers fast and powerful braking support, enhancing both reliability and fail-safe safety performance of the braking systems in heavy-duty and mobile equipment.

The valve is built with a modular, compact, and durable design, specifically engineered for the heavy demands of construction machinery. Its low internal leakage and fast response help maintain braking system stability during frequent starts and stops, extending equipment service life and making it suitable for heavy-duty applications.

The accumulator charging valve ensures that the accumulator always maintains a reserve of high-pressure hydraulic oil, allowing safe and effective emergency braking even if the engine shuts down, the hydraulic pump fails, or the main system malfunctions. Its efficient modular construction is designed to withstand tough mining environments enhancing brake safety.

The valve continuously charges the accumulator with sufficient high-pressure hydraulic oil, providing critical backup energy for service brakes. This guarantees reliable emergency braking capability even during engine shutdowns, pump failures, or main system breakdowns, preventing brake system collapse in demanding conditions.
