|---|---|
The SD15 is a heavy-duty, high-flow sectional directional control valve designed for advanced hydraulic systems that require robust performance and versatile multi-function control. Its modular, bolt-together sectional architecture allows custom configuration of individual working sections. It is widely used in large mobile machinery, high-capacity cranes, heavy-duty agricultural equipment, drilling rigs, and earthmoving vehicles.
Sectional Flexibility: Individual working sections can be added, removed, or serviced independently, making it easy to adapt the valve bank to changes in equipment layout.
Circuit Versatility: Supports parallel, tandem, or series configurations within the same valve block to control flow priority across different functions.
Comprehensive Safety Options: Equipped with a primary adjustable pressure relief valve in the inlet section, with the option to install independent auxiliary port relief and anti-cavitation valves on specific working sections.
Diverse Actuation Methods: Spools can be operated via standard manual levers, flexible remote cables, pneumatic pilots, hydraulic pilots, or proportional electro-hydraulic actuators.
Low Internal Leakage: Features highly precise spool clearances to minimize internal slippage, maintaining excellent load-holding capabilities.
System Expansion: Supports an optional high-pressure carry-over (HPCO / Power Beyond) plug to connect and supply oil to a downstream valve bank.
| Parameter Name | Metric | US Units | Notes |
|---|---|---|---|
| Nominal Flow | 120 ~ 140 L/min | 32 ~ 37 US gpm | Standard flow rate designed for valve body, suitable for high-flow and heavy-load hydraulic systems |
| Max Operating Pressure | 315 bar | 4600 psi | Applicable to standard Parallel and Tandem circuits |
