The model is РС25.20. It is a block consisting of separate sections of different purpose, assembled with tie rods (bolts).

Depending on the purpose of the sections, it has the following major modifications (as applied to loaders ОАО "Амкодор" и ЗАО "Орел-Погрузчик").


Manual valve-operated sectional spool valve can have different versions depending on the number and types of sections.

The execution of the hydrodistributor is determined by its full symbol.

In the symbol of the hydraulic distributor, the designation of the sections is indicated in the order of their installation, starting with the pressure one.

When installing several identical working sections in a row, before the designation of sections a number indicates their number.

The symbol for sectional hydraulic distributors is constructed according to the following scheme:

rs 2520 l t 1

An example of a symbol for a hydraulic distributor, consisting of a pressure section 20. two operating sections 01, one intermediate section 10.4, one working section 07 and a discharge section 30: a hydraulic distributor РС25.20-20-2x01-10.4-07-30 02.
