Sun Hydraulics Manifold Block | RDDA-LWN SCCA-LWN NFDC-LAN | Integrated Valve Assemblies

Sun Hydraulics Integrated Manifold Blocks & Valve Assemblies

Product Overview: Sun Hydraulics Manifold Blocks represent the premier solution for achieving modular and compact hydraulic system designs. By integrating high-precision screw-in cartridge valves with robust aluminum or steel manifolds, these assemblies execute multiple functions—such as relief, reduction, flow control, and load holding—within a single unit. This category features the high-performance combinations: RDDA-LWN+FAW/S, SCCA-LWN+E6V/S, NFDC-LAN+DAV/S, and FDCB-LAN+DNV/S.

These pre-configured assemblies are factory-tested and calibrated, drastically simplifying on-site installation while minimizing potential leak points. They are the ideal choice for industrial power units, mobile hydraulic control stacks, machine tool fixtures, and wind-power hydraulic systems.

Key Technical Advantages:

• Superior Integration: Consolidates complex hydraulic logic into a single block, significantly reducing plumbing requirements and system footprint.

• Precision & Stability: Utilizes Sun’s legacy cartridge valves, known for exceptional linear adjustment characteristics and minimal hysteresis.

• Versatile Manifold Materials: Available in high-strength aluminum (for medium pressure) or ductile iron (for high pressure) to suit diverse operational demands.

• Assembly Series Matrix:

  • RDDA Assemblies: Direct-acting relief structure providing ultra-fast response for overpressure protection.

  • SCCA Assemblies: Dual-function reducing/relieving logic ensuring stable secondary circuit pressure.

  • NFDC/FDCB Assemblies: Pressure-compensated flow control, maintaining consistent actuator speeds regardless of load fluctuations.
