Hydraulic Oil L-HV

Hydraulic Oil L-HV

Hydraulic oils L-HV are characterized by excellent anti-wear qualities, equivalent to the L-HM oils, and – very low oil viscosity dependence on temperature (upgraded viscosity and temperature qualities). The oils are formulated on the base of deeply refined, dewaxed and hydrorefined mineral oils received from crude oil straight-run distillation. The oils contain a properly selected package of anticorrosion, anti-oxidation and lubrication additives as well as demulsifying and antifoam attributes. Hydraulic oils L-HV are applied in power transmission systems and hydraulic control systems especially of moving, construction and vessel equipment.

Application

Guarantee

  • provides adequate protection of lubricated surfaces
  • has high anti-foaming qualities
  • provides sufficient air emission
  • has very good de-emulsifying qualities
  • provides hydrolytic stability
  • provides high level of filterability
  • maintains the lubricating systems clean
  • has very good viscosity and temperature properties
  • resistant to shearing
  • prolongs the durability of hydraulic system elements and protects then against wear and tear
