How to read FTFAXCN
Sun part numbers are the model followed by one code per option. Hyphens, slashes and spaces are only dividers, so FTFAXCN, FTFA-XCN, FTFA XCN are the same part.
| Model | FTFA — Sun Hydraulics 2-way, pilot-shifted, dual path, proportional throttle |
|---|---|
| Control | X — Not Adjustable |
| Spool Configuration | C — Normally Closed |
| 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
- These valves may be pressure compensated by an external, modulating, logic element. Use LR_C-XHN for a bypass circuit or LP_C-XHN for a restrictive circuit.
- The valve provides a degree of self-compensation and may be used as a flow control. To increase the accuracy of flow control, an external, modulating, logic element can be used to maintain a constant flow over a wider range of flows and pressures. See performance curves for additional information.
- The optional L control is a stroke adjustment that limits maximum flow.
- Ports 1 and 4 should be limited to 500 psi (35 bar).
- Pressure at port 4 directly opposes pressure at port 1.
- Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
- 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 FTFAXCN the same as FTFA-XCN?
Yes. Sun Hydraulics writes this part number as FTFAXCN. It is the model FTFA followed by the configuration code; hyphens, slashes and spaces are only dividers, so FTFAXCN, FTFA-XCN, FTFA XCN all refer to the same product.
Do you supply FTFAXCN in the UAE, GCC and India?
Yes. MultiFlow supplies genuine Sun Hydraulics cartridges, including FTFAXCN, 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.
How big is a drop of hydraulic oil?
There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
