Hydroraspredelitel R80-3/1-444, Kharkiv region.

The hydraulic distributor is intended for changing the direction or starting and stopping the flow of working fluid in hydraulic systems of machine tools, presses and other stationary machines, as well as in hydraulic systems of truck cranes,excavators and other mobile machines with pressure up to 32 MPa.
Hydrodistributors are operated on mineral oils with a kinematic viscosity of 10 to 40 mm 2/s.

Hydrodistributors serve to change the distribution of liquid flow to the power elements of the hydraulic drive in the direction from the pump station, as well as from the power elements to the drain line. Hydraulic struts, hydraulic jacks and auxiliary hydraulic cylinders are such power elements of hydraulic distributors.
