How to read LPJA8DN
Sun part numbers are the model followed by one code per option. Hyphens, slashes and spaces are only dividers, so LPJA8DN, LPJA8-DN, LPJA8 DN are the same part.
| Model | LPJA8 — Sun Hydraulics Normally open, modulating element with integral T-8A control cavity and pilot source from port 1 |
|---|---|
| Bias Pressure | D — 50 psi (3,5 bar) |
| 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. |
Bias Pressure options
- D — 50 psi (3,5 bar)

Technical features
- NOTE: With the -8 control option, the main stage valve should first be installed to the correct torque value. The T-8A pilot control valve should then be installed into the main stage valve to its required torque value.
- The -8 control option allows the pilot control valve to be incorporated directly into the end of the logic cartridge via the T-8A cavity. These pilot control cartridges are sold separately and include electro-proportional, solenoid, air pilot, and hydraulic pilot operation. See Pilot Control Cartridges.
- All ports will accept 5000 psi (350 bar).
- 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 LPJA8DN the same as LPJA8-DN?
Yes. Sun Hydraulics writes this part number as LPJA8DN. It is the model LPJA8 followed by the configuration code; hyphens, slashes and spaces are only dividers, so LPJA8DN, LPJA8-DN, LPJA8 DN all refer to the same product.
Do you supply LPJA8DN in the UAE, GCC and India?
Yes. MultiFlow supplies genuine Sun Hydraulics cartridges, including LPJA8DN, 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.
