Marine Hydraulic Oil （Ashless）
L-HV 15, 22, 32, 46, 68
PetroChina Lubricant Company’s L-HV Hydraulic Oil （ashless） series is produced with advanced technology. It has good anti-wear properties, oxidation and foam resistance, demulsibility and rust prevention properties, etc. It also has excellent low temperature performance.
L-HV Hydraulic Oil （ashless）series is mainly used in all types of medium and high pressure hydraulic systems in the engineering, mineral machinery and ocean ships in the cold and very cold areas, especially the extreme harsh working environment.
? Superior high viscosity index and low temperature performance.
? Excellent anti-wear properties, demulsibility and hydraulic stability.
? Corrosion and rust resistance, foam suppression and effectively eliminates air entrapment.
? Excellent filterability
? Good compatibility with all common sealing materials.
Bench Test and Mixing Test
? Vane pump test SH/T0307.
? FZG gear test SH/T0306.
? Indoor cold start bench test
? Outdoor long term field test in the cold area.
