Yuken Logic Valves

Yuken Logic Valves are placed in manifold blocks for directional control, flow rate control and pressure control. The cartridge valves include covers with pilot passages and can be used to create compact hydraulic power units and integrated hydraulic circuits with minimal internal leaking and no threat of hydraulic lock. The poppet type cartridge valves support high speeds, pressures and flow rates. They are shockproof and provide low pressure drop, shockless shifting, reduced piping vibration and noise. ISO standard cavity specifications.
