FAQ

What is the cracking pressure for this Dr.-Breit 405006.001 check valve?

The standard cracking pressure for this type of subplate-mounted check valve is typically between 0.5 and 5 bar. As Dr.-Breit does not specify it on the label, it is recommended to consult the manufacturer’s datasheet for the exact value to ensure it meets your system’s requirements.

Does this valve conform to a standard mounting pattern, like ISO 4401 or CETOP?

Yes, a DN6 (also known as NG6) subplate-mounted valve like this typically adheres to the ISO 4401-03 (CETOP 03) mounting standard. This ensures interchangeability with other manufacturers’ valves of the same size, such as the Bosch Rexroth Z1S 6 series.

What hydraulic fluids are compatible with this valve’s seals?

The standard seals used in these valves are usually NBR (Nitrile), which are compatible with mineral oil-based hydraulic fluids (HL, HLP). For use with synthetic fluids or other special media, it is crucial to verify the seal material with the manufacturer’s documentation.
