Manufacturer's description

Univis HVI is ExxonMobil's line of premium performance anti-wear hydraulic oils, characterised by unusually high viscosity indexes that maintain close viscosity control across wide temperature range applications. Because of their resistance to viscosity change, they are recommended for hydraulic systems subject to wide temperature variations that depend on uniform viscosity for hydraulic accuracy. Applications include hydraulic systems critical to uniform oil viscosity over a wide temperature range, hydrostatic transmissions and dash pots, fine instruments where torque increases from lubricant thickening cannot be tolerated, systems with close-clearance servo-valves, cold start-up and high operating temperature systems, and applications where rust and corrosion protection are valuable due to the presence of small amounts of water. Available grades include Univis HVI 13 and 26. Univis HVI oils offer optimum flow at sub-zero temperatures, resistance to shearing and viscosity loss that maintains system efficiency and minimises internal pump leakage at high temperatures and pressures, very good anti-wear protection for high-pressure vane, piston and gear pumps, and excellent oxidation stability that reduces deposit formation and improves pump and valve performance, developed in conjunction with major OEMs.

Applications

• • Hydraulic systems critical to uniform hydraulic oil viscosity over a wide temperature range • Hydrostatic transmissions and dash pots • They can also be used in fine instruments and other mechanisms where power input is limited and increases in torque due to the lubricant thickening cannot be tolerated • To reduce deposit formation in equipment where close clearance servo-valves are used • Systems where cold start-up and high operating temperatures are typical • Systems requiring a high degree of load-carrying capability and anti-wear protection • Applications where rust and corrosion protection are an asset such as systems where small amounts of water are unavoidable

Performance & benefits

• Univis HVI oils provide outstanding viscosity control over a wide temperature range. Their excellent oxidation resistance allows extension of oil and filter change intervals while assuring clean systems. Their high level of anti-wear properties and excellent film strength characteristics result in exceptional equipment performance that not only results in fewer breakdowns but helps improve production capacity. Their controlled demulsibility permits the oils to work well in systems contaminated with small amounts of water yet readily separate large amounts of water. The Univis HVI oils provide the following benefits: • Unusually high viscosity index and excellent viscosity control characteristics improves machine accuracy and reduces torque • Very low pour points maintains excellent fluidity conditions at low temperatures • Suitable for use in hydraulic equipment operating in very cold conditions, such as cold stores and mobile equipment operating in very cold climates • High performance and smooth hydraulic operations derived from uniform viscosity control, fast air release, very good foam control and good water separability • Exceptional rust and corrosion protection reduces the negative effects of moisture on system components • Effective oxidation stability reduces deposits and improves valve performance
