Product details

Doosan DX380/420/500 Boom Holding Valveis a critical hydraulic component designed for Doosan excavators, specifically models DX380, DX420, and DX500. Here's a detailed overview:

1. Purpose and Functionality

• Boom Holding: The valve ensures the boom remains stable and securely positioned during operation, preventing unintended movement or drooping, especially when the excavator is stationary or under load.

• Load Control: It helps manage hydraulic pressure to control the boom's movement precisely, enhancing operational safety and efficiency.

• Pressure Regulation: By regulating hydraulic pressure, the valve protects hydraulic components from damage due to overpressure, ensuring the longevity and reliability of the excavator's hydraulic system.

2. Technical Specifications

While specific technical data may vary based on the excavator model and valve version, typical characteristics include:

• Material: High-strength steel or alloy, ensuring durability and resistance to wear and corrosion.

• Pressure Rating: Designed to handle high hydraulic pressures, often exceeding 300 bar (4,351 psi), to accommodate the demands of heavy-duty excavation tasks.

• Flow Rate: Capable of managing significant hydraulic fluid flow to support the rapid movement of the boom and other hydraulic functions.

• Compatibility: Specifically engineered to integrate seamlessly with the hydraulic systems of Doosan DX380, DX420, and DX500 excavators.

3. Design Features

• Modular Construction: Allows for easy installation, maintenance, and replacement, reducing downtime and service costs.

• Advanced Sealing Technology: Utilizes high-quality seals to prevent hydraulic fluid leakage, ensuring efficient operation and minimizing environmental impact.

• Robust Design: Built to withstand harsh operating conditions, including extreme temperatures, dust, and moisture, common in construction and mining environments.

4. Applications

• Construction: Essential for tasks requiring precise boom control, such as digging, trenching, and material handling.

• Mining: Supports heavy-duty operations in mining environments, where reliability and durability are paramount.

• Demolition: Ensures stability and safety during demolition tasks, where the boom must remain firmly positioned under load.
