The Bosch Rexroth KKDER8NA/HN9V (R901069975) is a high-performance screw-in cartridge valve designed for hydraulic applications requiring precise control of the start, stop, and direction of flow. This directional spool valve is direct-operated with solenoid actuation and features a pressure-compensated design. It consists of a robust housing, a control spool, and a return spring. With a maximum operating pressure of 350 bar (5076 psi) and a nominal flow rate capacity, this valve ensures reliable performance under demanding conditions. The KKDER8NA/HN9V valve is equipped with wet-pin DC solenoids that provide smooth and efficient actuation. The control spool can be shifted by electrical signals to facilitate the flow in either direction, making it versatile for various hydraulic circuits. Additionally, the positive overlap design minimizes switching shocks during operation. A key feature of this model is its concealed manual override capability, which allows for manual operation in the absence of electrical power or during maintenance procedures. This ensures that operators have control over the hydraulic system at all times. The valve's FKM sealing material offers excellent resistance to high temperatures and chemical exposure, ensuring durability and longevity in harsh environments. It is compatible with various hydraulic fluids such as HL, HLP, HEES, and HEPG. Designed as part of the product family classification for directional spool valves and direct-acting positions, this model comes without an integrated coil which must be ordered separately. The KKDER8NA/HN9V fits into Sun TA cavities and has been engineered to meet stringent industry standards for performance and reliability in hydraulic systems.
