The SL10GA1-4X/ valve is manufactured by Bosch Rexroth and belongs to the Hy-Check Valves series. It serves as a pilot-operated element for blocking and controlled release of actuator lines in hydraulic automation. The nominal size is 10, letting it fit cavities designed for size-10 inserts. Flow moves freely from port A to port B, providing unrestricted actuator advance when no pilot signal is present. Reverse flow is locked until a control pressure of 5 bar reaches the pilot circuit. A built-in decompression feature opens the poppet in stages to limit pressure shocks during release. Pilot oil drains externally, so return oil is carried by a separate line. The primary control area A1 equals 1.33 cm², defining the pilot force needed for initial opening. Threaded connections simplify installation; ports A and B use G1/2 threads while pilot ports X and Y use G1/4 threads. The assembled unit weighs 2.1 kg, allowing manual handling during assembly.
Cleanliness must meet ISO 4406 code 20/18/15 to protect internal surfaces from particulate damage. The secondary control area A3 measures 3.8 cm², supplying additional pilot surface for full poppet lift once decompression is complete. Control volume on port X is 2.5 cm³, so the pilot line must deliver that oil quantity for the first stage of actuation. Port Y requires 2.0 cm³, completing piston movement during the release cycle. NBR seals provide compatibility with standard mineral hydraulic oils and common operating temperatures. A maximum operating pressure rating of 315 bar supports use in high-pressure circuits without derating. Together, the specified control areas and volumes establish predictable response time and pilot pressure gradients for the hydraulic system.
