I. Product Overview
The FVDA-XAN is a flow control valve produced by Sun Hydraulics in the United States, belonging to its cartridge valve series. This valve features an advanced floating structure design, offering high performance, high reliability, and a compact modular design. It is widely applied in hydraulic systems across engineering machinery, marine vessels, oil equipment, and other fields, enabling precise control of flow rates for accurate regulation of force, speed, and motion.
II. Product Features
1. Floating Structure Design: The valve's tail end is freely floating, reducing sensitivity to installation torque and preventing internal moving components from jamming, ensuring stable system operation.
2. Wear-Resistant and Fatigue-Resistant Components: Internal components are heat-treated for excellent wear resistance, impact resistance, and fatigue resistance, extending service life.
3. High Flow with Low Pressure Drop: Supports working pressures up to 350 bar and flow rates up to 720 L/min while maintaining a low pressure drop, enhancing system efficiency.
4. Modular Design: Facilitates easy integration into various hydraulic systems, reducing the need for cutting tools in manifold blocks and improving design flexibility.
5. Sealing and Material Technology: Some models are equipped with EPDM seals, suitable for phosphate ester hydraulic fluid systems, meeting specific operational requirements.
