Castrol Anvol PE 46 B
Castrol Anvol PE 46 B is a high performance fire resistant hydraulic fluid which is primarily intended for use in steam turbine governor and boiler control systems. It is based on butylphenyl phosphate esters selected for their excellent hydrolytic stability and contains carefully selected corrosion and oxidation inhibitors. It has excellent hydraulic performance and provides good fire risk protection.
Strong corrosion protection helps preserve metal surfaces against rust and chemical attack, supporting equipment longevity in environments where moisture or aggressive contaminants may be present.
The chlorine- and heavy-metal-free formulation reflects a modern approach to industrial fluid design, supporting an improved environmental profile and reduced waste disposal costs.
The formulation is engineered to maintain engine and component cleanliness, helping to prevent deposit build-up and supporting efficient operation throughout the service interval.
Castrol Anvol PE 46 B is suitable for use in hydraulic systems where, in the event of leakage or pipe fracture, there is risk of fire and where water containing fluids are unsuitable due to temperature limitations or other reasons. It is specifically designed for use in the electro-hydraulic governor control systems of team turbines, including systems using fine tolerance servo valves. Castrol Anvol PE 46 B was developed to eliminate service problems in high pressure systems resulting from spool valve erosion/corrosion – fluid leakage and loss of response – by possessing the properties known to minimize this effect, notably high resistivity, low chlorine content and a high level of fluid cleanliness.
Castrol Anvol PE 46 B is manufactured to Castrol’s standard tolerances; users should consult the safety data sheet for handling, storage and disposal guidance.
