The Hydac SBVE-R10-1/2-11 is a high-performance, pilot-operated check valve designed as a screw-in cartridge. It is engineered to block oil flow from port 2 to port 1, ensuring zero leakage, while allowing free flow from port 1 to port 2. By applying sufficient pressure to the pilot port (port 3), the poppet opens, permitting flow from port 2 to port 1. This valve is ideal for load-holding applications in hydraulic systems, preventing cylinder drift and ensuring operational safety and stability. Its robust cartridge design allows for easy integration into custom manifold blocks, saving space and reducing potential leak points.
