How to read RSJSLAN
Sun part numbers are the model followed by one code per option. Hyphens, slashes and spaces are only dividers, so RSJSLAN, RSJS-LAN, RSJS LAN are the same part.
| Model | RSJS — Sun Hydraulics Pilot-operated, balanced poppet sequence valve |
|---|---|
| Control | L — Standard Screw Adjustment |
| Adjustment Range | A — 100 - 3000 psi (7 - 210 bar), 1000 psi (70 bar) Standard Setting |
| 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
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Pilot flow continues to increase as the pressure at port 1 (inlet), relative to the pressure at port 3 (drain), rises above the valve setting.
- The main stage orifice is protected by a 150 micron stainless steel screen.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Because the modulating occurs inside the cartridge these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- 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 RSJSLAN the same as RSJS-LAN?
Yes. Sun Hydraulics writes this part number as RSJSLAN. It is the model RSJS followed by the configuration code; hyphens, slashes and spaces are only dividers, so RSJSLAN, RSJS-LAN, RSJS LAN all refer to the same product.
Do you supply RSJSLAN in the UAE, GCC and India?
Yes. MultiFlow supplies genuine Sun Hydraulics cartridges, including RSJSLAN, 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 does Sun mean by the term sequencing?
A sequence valve opens when the pressure at port 1 exceeds the setting of the valve. When pressures at port 1 and port 2 both exceed the setting of the valve the valve goes full open, or sequences. When this happens flow can go in either direction, just so long as port 1 stays above the setting.
What are the tolerances on pressure settings for Sun's pressure control valves?
Pressure setting tolerances are listed in our Performance Data page. A link to this page can also be found in the Additional Resources tab of the applicable product page.
What parts of the Sun cartridge valve are field serviceable?
