description: This final qualification work is devoted to the use of biodegradable and environmentally acceptable fluids as hydraulic oils. The paper carefully analyzed the various types of existing biodegradable and environmentally acceptable fluids used as hydraulic fluids. Powered by existing biodegradable and environmentally friendly liquids. A description of the various types of existing biodegradable and environmentally acceptable liquids, their features is made, the reasons and consequences of replacing traditional mineral oils with biodegradable and environmentally acceptable liquids are indicated. A comprehensive comparison of existing brands of biodegradable and environmentally acceptable liquids with existing brands of mineral oils was made. Separately, the task of studying the behavior of biodegradable fluids of the HEES type in hydraulic systems is singled out. To solve this problem, the path of mathematical modeling of the behavior of a HEES type fluid in hydraulic systems and specifically in hydraulic balancing valves of the CBV type was chosen. The possible effect of HEES type liquids on CBV type valves has been evaluated.
