HV 46 Low Temperature Anti Wear Hydraulic Lubrication High Viscosity Index Cold Region Fluid

HV 46 Low Temperature Anti Wear Hydraulic Lubrication High Viscosity Index Cold Region Fluid

HV 46 Low Temperature Anti-Wear Hydraulic Oil High Viscosity Index Cold Region Fluid

Kunlun HV low temperature anti-wear hydraulic oil is a high performance hydraulic fluid developed by PetroChina for equipment that must operate reliably in cold climates and wide temperature swings. It is blended from deeply refined, high viscosity index base stocks together with a carefully selected multifunctional additive package through an advanced production process, giving the oil dependable low temperature fluidity without sacrificing anti-wear protection.

Product Introduction

This low temperature anti-wear hydraulic oil is specifically intended for open-air, cold region and large temperature variation environments, as well as for demanding medium and high pressure hydraulic systems. Kinematic viscosity at 40 °C is used to classify the product into grades 32, 46 and 68, allowing users to match the low temperature anti-wear hydraulic oil to the ambient conditions and the requirements of their machinery.

Because cold starts place severe stress on pumps and valves, a low temperature anti-wear hydraulic oil must retain good pumpability while still forming a strong lubricating film. Kunlun HV is formulated to deliver exactly this balance, so hydraulic equipment can be started and operated smoothly even when temperatures drop sharply.

Technical Specifications

Key Performance Advantages

• Excellent low temperature performance: the low temperature anti-wear hydraulic oil keeps flowing and lubricating at low ambient temperatures, enabling easy cold starts.
• High viscosity index: viscosity stays stable across a wide temperature range, so the low temperature anti-wear hydraulic oil supports consistent system response.
• Reliable anti-wear protection: protects pumps, motors and valves from wear under harsh operating conditions.
• Good thermal and oxidation stability: resists oil degradation and extends oil drain intervals.
• Good demulsibility and anti-foam behaviour: separates water quickly and releases air to keep the system steady.
• Good filterability and seal compatibility: supports clean operation and helps prevent leakage.

Recommended Applications

• Mobile hydraulic systems that work outdoors in cold climates and open-air sites.
• Construction, mining and agricultural machinery operating in cold regions.
• Hydraulic systems exposed to wide ambient temperature changes.
• Machine tools and industrial hydraulic equipment running at medium to high pressure.

Frequently Asked Questions

Q: What viscosity grades does this low temperature anti-wear hydraulic oil come in?
A: Kunlun HV is classified by 40 °C kinematic viscosity into grades 32, 46 and 68, so users can select the grade that suits their climate and equipment.

Q: When should this high viscosity index hydraulic fluid be used instead of a standard HM oil?
A: Choose this low temperature anti-wear hydraulic oil when equipment operates in open-air or cold region conditions, or when ambient temperatures vary widely.

Q: Which systems is this hydraulic fluid suitable for?
A: It suits medium and high pressure hydraulic systems, including mobile machinery and industrial equipment that must start reliably in the cold.

Q: Does cold weather reduce the protection provided by this anti-wear hydraulic oil?
A: No. The high viscosity index base stock maintains viscosity stability, allowing the low temperature anti-wear hydraulic oil to keep protecting components even as temperatures fall.
