Castrol Anvol PE 46 B
Castrol Anvol PE 46 B is a high performance fire resistant hydraulic fluid primarily intended for use in steam turbine governor and boiler control systems. Based on butylphenyl phosphate esters selected for their excellent hydrolytic stability, and containing carefully selected corrosion and oxidation inhibitors, it delivers excellent hydraulic performance together with good fire risk protection. It is specifically designed for electro-hydraulic governor control systems of steam turbines, including systems using fine tolerance servo valves, and was developed to eliminate service problems in high pressure systems resulting from spool valve erosion or corrosion.
APPROVAL STATUS
| •Meets the requirements of major OEMs such as General Electric, Siemens, Mitsubishi Hitachi Power Systems, and Alstom |
| •Meets the requirement of FM Global against Standard 6930 for "Less flammable hydraulic fluids" |
| •Meets the requirements of ISO Standard 12922 and ASTM D4293 for HFDR-type fire-resistant hydraulic fluids |
KEY FEATURES
| •Offers good fire risk protection in systems where fire resistance is vital and where water-containing fluids are unsuitable due to temperature limitations or the need to maintain a high hydraulic system pressure |
| •High flash point, fire point, and auto-ignition temperature provide excellent fire resistance |
| •High resistivity eliminates spool valve corrosion/erosion due to electrokinetic effects |
| •Low chlorine level minimises valve erosion |
| •High level of fluid cleanliness — minor amounts of particulate contamination can cause abrasive wear, filter blockage, and valve sticking |

COMPATIBILITY
| •Compatible with all metals commonly found in electro-hydraulic control systems |
| •Aluminium components should be hard anodized; copper and copper alloy components should be kept to a minimum |
| •Suitable seal materials: fluoropolymers (Viton), butyl rubber, PTFE, and ethylene propylene rubber (under certain operating conditions) |
| •Where paint materials are used, they should be epoxy resin based |
STORAGE & HANDLING
| •Periodic measurement of the fluid neutralisation number is recommended during service, as this provides a good guide to product degradation |
| •Rigorous flushing is essential when converting systems from other fluids to phosphate esters; remove all scale and check filters, hoses, seals, and internally painted surfaces for compatibility with the new fluid |
| •Avoid prolonged or repeated contact with skin; wash thoroughly after handling |
| •Store all packages under cover. Where outside storage is unavoidable, lay drums horizontally to avoid water ingress and drum marking damage. Do not store above 60°C, exposed to hot sun or freezing conditions |
