Univis HVI 26

Univis™ HVI Series is a line of premium performance anti-wear
hydraulic oils characterised by their unusually high viscosity indexes.
They are engineered to maintain close viscosity control over wide
temperature range applications. Because of their resistance to
viscosity change, Univis HVI oils are recommended for hydraulic
systems that are subject to wide temperature variations. Many of
these systems are sensitive to changes in viscosity of the hydraulic
oil, since they depend on uniform viscosity for hydraulic accuracy.
They exhibit optimum flow characteristics at sub-zero temperatures
and the oils are resistant to shearing and viscosity loss so that system
efficiency is maintained and internal pump leakage is minimised
at high operating temperatures and pressures. These high quality
hydraulic oils also provide very good anti-wear protection for
high-pressure vane, piston and gear pumps. The Univis HVI oils
are designed with excellent oxidation stability reducing deposit
formation and improving pump and valve performance. They were
developed in conjunction with the major OEM’s to meet the stringent
requirements of severe hydraulic systems using high pressure, high
output pumps as well as handling the critical requirements of other
hydraulic system components.
