|---|---|
The SD8 is a high-performance, modular sectional directional control valve designed for mid-to-high flow hydraulic systems. Its segmented, bolt-together architecture offers exceptional flexibility, allowing multiple functions to be combined into a single bank. It is commonly utilized in mobile machinery, waste management vehicles, truck cranes, and heavy agricultural equipment requiring precise multi-actuator control.
Modular Assembly: Individual working sections can be added, removed, or interchanged, allowing field modifications and easy maintenance.
Circuit Variety: Supports parallel, tandem, or series configurations within the same valve assembly to control oil priority.
Integrated Safety Options: Features a built-in main pressure relief valve in the inlet, with optional auxiliary port relief and anti-cavitation check valves on individual sections.
Versatile Actuation: Can be operated via manual levers, cable controls, pneumatic pilots, hydraulic pilots, or electro-hydraulic actuators.
High Precision Spools: Employs finely machined, interchangeable spools with low internal leakage (3 cm³/min at 100 bar).
Power Beyond Option: Supports an optional high-pressure carry-over (HPCO) plug in the outlet to link and power additional downstream valves.
