L-HV 32, 46, 68, 100 series of low-temperature hydraulic oil products
Short Description:
Product Overview: This product is blended using high-quality hydrotreated base oil and compatible multifunctional additives, employing advanced production technology.
Performance Characteristics:
* Excellent viscosity-temperature properties, low-temperature start-up performance, low-temperature flow properties, and shear stability, effectively extending the oil’s service life;
* Excellent anti-wear properties, effectively reducing hydraulic pump wear and extending the pump and system’s operational life;
* Excellent oxidation stability, rust and corrosion prevention, demulsification properties, and anti-foaming properties;
* Excellent hydrolytic stability and filterability, reducing filter clogging;
* Excellent rubber compatibility, effectively protecting sealing materials and preventing leaks.
Applications: Suitable for lubrication of medium- and high-pressure hydraulic systems in open-air, cold-region, and harsh operating conditions with large temperature variations; such as hydraulic systems in engineering machinery, construction machinery, mining machinery, oilfield machinery, ships, and vehicles.
