D03 Series Subplate Bottom Ported Ductile Cast Iron – SD03-6FP-B

The Hyvair SD03-6FP-B is a D03 (NG6) hydraulic subplate manufactured from high-strength ductile cast iron and engineered to provide a durable, reliable mounting solution for D03 directional control valves in demanding hydraulic systems. Designed to accommodate industry-standard D03 valve mounting patterns, this subplate serves as a robust interface between the valve and hydraulic circuit, ensuring secure installation and efficient fluid distribution.

The 6FP configuration features 3/8-inch female NPT ports with bottom porting, offering installation flexibility and making it well-suited for a variety of hydraulic system layouts where clean plumbing and compact system design are important. Its bottom-ported configuration helps simplify hydraulic routing, reduce external plumbing complexity, and create a more organized hydraulic assembly.

Rated for operating pressures up to 5,000 PSI and flow rates up to 5 GPM, the SD03-6FP-B is designed to perform reliably in high-pressure hydraulic applications where strength and durability are critical. The ductile cast iron construction provides significantly greater structural integrity and pressure-handling capability than aluminum alternatives, making it particularly well-suited for severe-duty industrial environments, mobile equipment, hydraulic power units, manufacturing machinery, and other applications subject to high operating pressures and demanding service conditions.

Precision-machined sealing surfaces and porting ensure dependable valve mounting and leak-free operation, while the rugged construction helps resist vibration, shock loading, and long-term wear. By providing a stable and durable foundation for D03 directional control valves, the SD03-6FP-B contributes to improved system reliability, easier maintenance, and extended service life in critical hydraulic applications.

For hydraulic systems where high pressure, durability, and dependable performance are essential, the Hyvair SD03-6FP-B offers a proven ductile iron subplate solution designed to withstand the rigors of continuous industrial and mobile equipment operation.
