Product details

the HVSP Series Load-sensing Multi-way Control Valve:

I. Working Principle

The HVSP Series Load-sensing Multi-way Control Valve is a high-performance hydraulic control component that automatically adjusts flow based on load changes. When the load in the hydraulic system increases, the load-sensing element perceives the change and adjusts the position of the valve spool and the cross-sectional area of the flow passage by increasing pressure compensation to maintain appropriate speed and force output. When the load decreases, it reduces pressure compensation and adjusts the flow to avoid excessive speed and force.

II. Structural Characteristics

• Modular Design: The HVSP Series valves are based on a modular design concept, allowing flexible combination of valve plates with different control modes to meet various customer requirements.

• Multiple Control Modes: Including manual control, hydraulic control, electro-hydraulic proportional control, CAN bus control, etc., providing customers with more options.

• Integrated LVDT Valve Spool Displacement Feedback Closed-loop Control Circuit: Offers high control accuracy, comparable to servo valves.

• Adopting J1939 or CANopen Protocols: Supports online fault diagnosis, as well as power failure, overload, overcurrent, and reverse protection, ensuring safe operation of the equipment.

III. Performance Parameters

Taking HVSP25 as an example, its rated pressure reaches 350bar, with a rated flow of 400L/min, and the maximum flow provided by a single valve can reach 200L/min. This valve adopts pre-valve pressure compensation and can be applied to both fixed and variable displacement pump systems.

IV. Application Fields

The HVSP Series Load-sensing Multi-way Control Valve is widely used in construction machinery, ships, energy extraction, tunnel machinery, metallurgy, industrial manufacturing, and other fields. Especially in large equipment such as cranes, rotary drilling rigs, and shield tunneling machines, the HVSP Series valves can accurately control the flow of the hydraulic system according to load changes, achieving smooth operation, reducing energy consumption, and extending the service life of the equipment.

V. Product Advantages

• High-Precision Control: Integrated with advanced CAN bus electro-hydraulic proportional drivers or CAN bus servo motor controls, it achieves precise flow (speed) adjustment through closed-loop control of valve spool displacement.

• Energy-saving and Environmental Protection: It can monitor load changes in real-time and respond quickly, adjusting the flow to balance system pressure and reduce energy consumption.

• Improved System Performance: Greatly enhances the accuracy and anti-interference ability of the electro-hydraulic system, thereby improving the performance and reliability of the electro-hydraulic system.

In summary, the HVSP Series Load-sensing Multi-way Control Valve plays an important role in the development of modern construction machinery due to its superior performance and wide range of applications.
