Technical features
- Leakage listed in technical data is for each path.
- Pressure at port 6 directly opposes port 1.
- 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 DDDGXCN the same as DDDG-XCN?
Yes. Sun Hydraulics writes this part number as DDDGXCN. It is the model DDDG followed by the configuration code; hyphens, slashes and spaces are only dividers, so DDDGXCN, DDDG-XCN, DDDG XCN all refer to the same product.
Do you supply DDDGXCN in the UAE, GCC and India?
Yes. MultiFlow supplies genuine Sun Hydraulics cartridges, including DDDGXCN, 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?
