Request a Quote
- Electro-hydraulic proportional flow control valves integrate a dual-section, multi-way valve structure, offering a cohesive solution for complex hydraulic systems
- These flow control valves provide various valve core functions that users can select and combine according to their needs
- The valve cores feature precisely controlled grooves, delivering efficient speed control performance and superior repeatability
- Incorporate load independent flow dividing (LIFD) control, which ensures that the flow rate is unaffected by load pressure, leading to energy savings and comfortable operation.
- Equipped with a return oil regeneration function, the valve saves energy and prevents cavitation, enhancing system efficiency.
- It includes built-in cartridge-style main safety valves, overload valves, and replenishment valves, ensuring good versatility and ease of maintenance.
- Suitable for both constant and variable systems; ideal for various hydraulic applications.
Applications
- Wheel loaders
- Excavators
- Bulldozers
- Telescopic handlers
- Material handling equipment
