Hydraulic fluid DALY-5y
aviation oil
Description
Working fluid NGZH-5u – synthetic explosion and fire, erosion-based liquid mixture of phosphoric acid esters containing additives that enhance viscosity, antigidroliznye, anti-oxidation, anti-corrosion and antierosion properties
Applications
Use in hydraulic IL-86, IL-96, TU-204, and others. The temperature range of use of the liquid-NGZH 5y is -60 … + 150 ° C at nominal pressures up to 21 MPa. The liquid has a temperature of 595-630 ° C self-ignition, burns in the flame slowly, and does not support combustion flame does not spread. DALY liquid-5y fully aligned with liquids DALY DALY-4-4y.
