?

The 25160AF is a bidirectional plate-type balance valve independently developed by our company, specifically designed for load balancing in hydraulic systems of construction machinery.? Its core application is in circuits requiring gravity load balancing, such as crane booms, excavator arms, and aerial work platform lifting mechanisms.

?

It features an integrated ductile iron valve body and a high-pressure composite sealing structure, integrating bidirectional balance control functionality. It precisely prevents load overspeed descent, eliminates flow lag, and provides reliable pressure holding performance, preventing no-load drift and ensuring safe and stable equipment operation. This valve is designed for plate mounting, offering convenient installation and excellent sealing performance. It is compatible with various imported and domestic construction machinery and can directly replace equivalent components from major international brands, combining durability with cost-effectiveness. It is an ideal component for hydraulic systems in heavy-duty applications.
