How to read DCFDXCN
Sun part numbers are the model followed by one code per option. Hyphens, slashes and spaces are only dividers, so DCFDXCN, DCFD-XCN, DCFD XCN are the same part.
| Model | DCFD — Sun Hydraulics 4-way, 2-position, pilot-to-shift, detented, directional valve |
|---|---|
| Control | X — Standard Pilot |
| Spool Configuration | C — Blocked Crossover |
| Seal Material | N — Buna-N |
| Material / coating | Add /AP (stainless steel, passivated) or /LH (mild steel, zinc-nickel) to the end; no suffix is the standard finish. |

Technical features
- All ports will accept 5000 psi (350 bar), including the x and y pilot ports (port 5 and port 6).
- Leakage listed in technical data is for each path.
- The pilot ports, 5 and 6, are positively sealed from the work ports.
- Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
- Incorporates the Sun floating-style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.

Frequently asked questions
Is DCFDXCN the same as DCFD-XCN?
Yes. Sun Hydraulics writes this part number as DCFDXCN. It is the model DCFD followed by the configuration code; hyphens, slashes and spaces are only dividers, so DCFDXCN, DCFD-XCN, DCFD XCN all refer to the same product.
Do you supply DCFDXCN in the UAE, GCC and India?
Yes. MultiFlow supplies genuine Sun Hydraulics cartridges, including DCFDXCN, to customers in the UAE, the wider GCC and India. Use Add to Enquiry on this page for availability, lead time and a quotation.
Can I get the datasheet and CAD files?
Yes. The datasheet, technical reference sheets and CAD files (DXF, DWG, STP) are listed in the Downloads section of this page.
Direct acting or pilot operated - what do I use?
Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
How big is a drop of hydraulic oil?
There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
What parts of the Sun cartridge valve are field serviceable?
