Castrol Anvol PE 46 XC

Description

Anvol PE 46 XC 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 triaryl 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.

Application

Anvol PE 46 XC 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 steam turbines, including systems using fine

tolerance servo valves. Anvol PE 46 XC 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. Physical properties such as

foaming, air release and demulsibility are also carefully controlled within turbine manufacturers’ specified limits.

Features and Benefits

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 provides excellent fire resistance.

High resistivity eliminates spool valve corrosion/erosion due to electrokinetic effects.

Low chlorine level minimizes valve erosion.

High level of fluid cleanliness - minor amounts of particulate contamination can cause abrasive wear, filter

blockage and valve sticking.

Long record of trouble free service in highly demanding hydraulic control systems on turbines.
