How to read FLFAXDN

Sun part numbers are the model followed by one code per option. Hyphens, slashes and spaces are only dividers, so FLFAXDN, FLFA-XDN, FLFA XDN are the same part.

Technical features

  • Differential crush pressure is 3000 psid (210 bar).
  • The flow path is Port 2 to Port 1 only.
  • Installation directly above the subplate will protect the entire valve stack from particles.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • Surface type element features a 304 stainless steel mesh media. All internal components are 304 stainless steel.
  • Surface Type elements have a 40 micron nominal rating (63 micron absolute).
  • Surface Type elements are designed to capture errant particles that may not be trapped in the main system filter or particles resulting from a component failure.
  • With a correctly assembled system, Surface Type elements will be unnoticed during regular operation, but will provide protection from sudden component failure.
  • Surface Type (Last Chance) elements have a single layer stainless steel mesh supported by perforated sheet tube.

Frequently asked questions

Is FLFAXDN the same as FLFA-XDN?

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

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

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

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.
