Description

Engineered for demanding circuits, the D05 Series Subplate Bottom & Side Ported Ductile Cast Iron (Part SD05-8FS-S) provides a rugged, reliable mounting base for NFPA D05 / ISO 4401‑05 directional control valves. Machined from high‑strength ductile cast iron (D4512) and rated for system pressures up to 5000 psi, it is ideal for heavy‑duty industrial, mobile, and high‑cycle hydraulic applications where durability and leak‑free performance are critical.

This subplate features both bottom and side ports, giving you flexible plumbing options to best suit tight spaces, retrofit installations, or new manifold layouts while keeping hose routing clean and accessible. The standardized D05 interface simplifies valve mounting, alignment, and replacement, allowing fast change‑outs and straightforward field service without reworking piping.

Precision machining helps ensure accurate sealing surfaces, reduced pressure drop, and consistent flow paths for dependable valve performance over the life of the system. The ductile iron construction offers superior fatigue resistance and toughness compared to standard gray iron, supporting long service life under shock loads and pressure spikes common in high‑pressure circuits.

Use the SD05-8FS-S when you need:

– A robust D05 subplate compatible with most industry‑standard D05 directional valves
– A compact, bottom‑and‑side ported layout to streamline hose and tube connections
– High working pressure capability for severe‑duty or continuous‑duty equipment

Whether you’re building new power units, upgrading existing valve banks, or standardizing on NFPA/ISO mounting patterns, this D05 ductile iron subplate delivers a dependable, heavy‑duty foundation for your hydraulic control valves.
