Technical features

  • The position switch in this valve provides confirmation that the valve is closed.
  • This cartridge is supplied as a sealed, factory set unit and is not field serviceable. Any tampering will violate the product warranty.
  • When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.
  • All ports will accept 5000 psi (350 bar).
  • An optional protective cover, with mounting hardware included, may be ordered separately. See kit number: 991-043.
  • 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 CXFHZCN the same as CXFHZ-CN?

Yes. Sun Hydraulics writes this part number as CXFHZCN. It is the model CXFHZ followed by the configuration code; hyphens, slashes and spaces are only dividers, so CXFHZCN, CXFHZ-CN, CXFHZ CN all refer to the same product.

Do you supply CXFHZCN in the UAE, GCC and India?

Yes. MultiFlow supplies genuine Sun Hydraulics cartridges, including CXFHZCN, 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.

I need to discharge a large accumulator. How can I increase the capacity of my discharge circuit?

Because of the very high ratio, the COFO has limited capacity. The discharge path is across a .050 inch (1,3 mm) diameter orifice. If you have large accumulators combined with low precharge pressures, this may not discharge the energy quickly enough. Using the COFO XDN cartridge in conjunction with an LODA XDN will provide capacity for larger applications.

How big is a drop of hydraulic oil?  

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

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.

What parts of the Sun cartridge valve are field serviceable?
Only external seals are serviceable.  Sun offers replacement seal kits for all cartridge models. The applicable kit part number can be found in the product page's Technical Data table or by using our Cartridge Seal Kit search function located under Accessories. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.
