The SD11 is a highly versatile, heavy-duty monoblock directional control valve designed for medium-flow hydraulic applications. Unlike sectional valves, its single-piece cast-iron construction provides exceptional compactness, leak resistance, and structural rigidity. It is widely used in applications such as mobile and tipping vehicles, conveying equipment, compact multi-function cranes, refuse compactors, and vehicle transporters.
Ultra-Compact Power Density: Provides heavy-duty, high-pressure sectional customization features usually reserved for massive machinery, but scaled down into a lightweight housing that fits into severely restricted installation spaces.
Individual Port Valving (Optional): Every working slice can be optionally configured with independent secondary anti-cavitation valves or auxiliary shock/overload relief valves. This lets you restrict pressure on one delicate micro-cylinder without lowering full system pressure for the rest of the machine.
Integrated Safety Elements: Features a global adjustable pressure relief valve built directly into the inlet front section, alongside independent internal load-holding check valves in every segment to eliminate accidental load sagging.
Power Beyond / Closed-Center Adaptable: The outlet tail section can easily convert between traditional open-center configurations, closed-center loops (for variable pumps), or Power Beyond (Carry-Over) setups using simple screw-in adapter plugs.
