Sun Hydraulics Cartridge Valves & Cross-Reference

Sun Hydraulics, founded in 1970 and headquartered in Sarasota, Florida, builds screw-in hydraulic cartridge valves and integrated manifold systems for pressure, flow, logic, directional, and load control. Helios Technologies acquired the company in 2018, and the line remains in active production, serving industrial and mobile OEM applications with cartridges rated to 5,000 psi and flows to 400 gpm across five cartridge size series. Northern Hydraulics supplies and cross-references Sun Hydraulics cartridge valves and manifold assemblies; original parts stay in continuous production and route through Sun’s published cross-reference system.

Cross-Referencing Sun Hydraulics Parts

Sun Hydraulics has no discontinued models. Every original part number stays in the catalog and remains available to order, so when you have a legacy code in hand the path to the current equivalent is a documented one. Sun publishes official Valve Assembly Package Cross Reference documentation that maps old model codes to current ones, splitting an older single assembly code into a current cartridge plus a body. The legacy YPEF-ABN-BA assembly, for example, is now ordered as Cartridge PBFC-ABN plus Body BB2.

If you are holding an old Sun part code, a faded label, or a valve pulled from a machine with no paperwork, send us the markings. We work from Sun’s cross-reference tables and the 790 Part Numbering System to identify the current cartridge and body numbers, then quote the replacement. Request a Sun Hydraulics cross-reference quote with whatever code, photo, or application detail you have, and we will match the equivalent part.

Sun Hydraulics Product Lines & Series

Sun’s catalog is organized around five cartridge size families plus a set of electronic, coil, and manifold series:

• Series 0, 1, 2, 3, and 4 screw-in cartridge valves, with Series 4 PLUS for high-flow circuits
• FLeX Series solenoid valves (DWBF, DMB, DNB, DFB, DTAF, DTBF, FPB, FREP)
• Electro-proportional cartridges and pilot-operated relief valves
• Counterbalance valves and pressure control cartridges
• 740 Series coils (low and high power) and 747 Series hazardous-location coils
• Standard, custom, line-mount, sandwich, and subplate manifold assemblies

Part numbers across these families follow Sun’s 790 Part Numbering System, which is the basis for matching a legacy code to its current cartridge-plus-body equivalent. Tell us the series and the markings on the valve and we will work it back to an orderable part. Request a quote on any Sun cartridge, coil, or manifold.
