Product Overview
The Parker CSV08 321 81 / 026-67040-0 is a high-performance screw-in cartridge valve belonging to Parker’s CSV series of two-way slip-in cartridge valves, engineered for directional control and load-holding functions within demanding industrial hydraulic circuits. Operating on a poppet-and-sleeve working principle, this cartridge valve is piloted by a separate directional control valve to open or close the main flow path, delivering fast, leak-free switching of high flows at elevated pressures. With its compact screw-in cartridge format, the CSV08 321 81 integrates directly into a machined manifold cavity, eliminating external piping, reducing leakage points, and enabling space-saving, high-density hydraulic power unit designs. It serves as a critical control element in systems requiring reliable directional control, pilot-operated unloading, and secure load holding.
