DCV45DQ-5OT-DQK Electro-Hydraulic Multi-Section Directional Control Valve

Product Advantages & Applications

1. High Pressure and Wide Flow Range for Demanding Applications

The DCV45DQ-5OT-DQK is engineered as a high-pressure directional control valve, operating at 250 bar with a broad 40-120 L/min flow range. This makes it ideally suited for heavy-duty construction equipment like excavators and cranes, where high pressure translates to greater force for digging and lifting, while the wide flow range allows for optimized control of both speed and power. This capability directly enhances productivity by enabling faster cycle times without sacrificing performance. For equipment owners, this means completing more work in less time, improving project timelines and profitability. The high-pressure design also contributes to a more compact system layout, saving valuable space in complex machinery. Choose the DCV45DQ-5OT-DQK to power your most challenging applications with efficiency and strength.

2. Modular Monoblock Design for Customized Control Solutions

Flexibility is at the core of this valve's design. As a modular multi-section directional valve, it can be configured with 1 to 7 sections to create a custom hydraulic control manifold tailored to specific machine functions. This is essential for modern machinery like concrete pump trucks and advanced loaders that require precise, coordinated control of multiple actuators—such as booms, arms, and buckets—from a single, integrated unit. This modularity drastically simplifies the overall hydraulic system, reducing the complexity of piping and connections. For our clients, this means they can specify the exact number of sections needed, avoiding cost overruns from unnecessary functions, while also benefiting from easier maintenance and future upgrades, as individual sections can be serviced or replaced independently.

3. Multiple Integrated Control Methods for Operational Versatility

This valve's standout feature is its integration of manual, pneumatic, solenoid, and electro-hydraulic control methods, making it a truly versatile electro-hydraulic control valve. This provides unparalleled operational flexibility. For example, in a refuse collection vehicle, operators can use manual control for precise positioning during loading and then switch to automated electro-hydraulic control for efficient transport and dumping cycles. This adaptability allows a single machine to excel in varied tasks and environments. The inclusion of electro-hydraulic remote control is particularly significant, as it paves the way for semi-automated or fully remote-operated machinery, meeting the growing industry trend towards smarter, safer, and more efficient construction sites and industrial operations.

4. Robust Construction for Harsh Environment Durability

Built to endure, the DCV45DQ-5OT-DQK is a reliable hydraulic valve for off-road equipment. It utilizes high-strength materials and advanced sealing technology to withstand the extreme challenges of construction, mining, and drilling sites, including intense vibration, abrasive dust, and mechanical shock. The superior sealing effectively prevents fluid leaks and blocks contaminant ingress, which are primary causes of hydraulic system failure. For our customers, this robust construction translates directly into higher machine availability (uptime) and a longer service life. It reduces the frequency of failures and the associated maintenance costs, ensuring that equipment remains operational and profitable even in the world's most challenging working environments.

5. Wide Temperature and Viscosity Range for All-Climate Reliability

The valve's exceptional operational breadth, from -40°C to 80°C and with fluid viscosities of 12-400 mm²/s, makes it an all-climate hydraulic control valve. This ensures consistent and reliable performance regardless of geographic location or seasonal changes, from freezing arctic winters to scorching desert summers. This is a critical advantage for mobile equipment that operates across different regions, such as over-the-road trucks and rental equipment. Clients benefit from simplified maintenance, as there is no need to change hydraulic components or fluids with the seasons. Furthermore, the wide viscosity tolerance provides flexibility in hydraulic fluid selection, which is a significant operational advantage in remote areas where specific oil grades may not be readily available.

6. Integrated Safety Features for Enhanced System Protection

Safety and reliability are engineered into the DCV45DQ-5OT-DQK with its integrated safety and overload valves. These features provide critical protection for the entire hydraulic system. In applications like crane operation, the safety valve prevents dangerous pressure build-up in the event of an overload, while the overload valve protects cylinders and motors from shock loads that can cause catastrophic damage. For the end-user, this integrated safety package enhances operational safety, reduces the risk of costly equipment damage, and lowers total system cost by eliminating the need for additional, external safety components. The precise and rapid response of these valves ensures protection is both immediate and accurate, contributing to superior system stability and longevity. Invest in a valve that prioritizes safety and protects your valuable equipment.
