STEAM CYLINDER OIL

Shell Valvata J

Shell Valvata Oil J are quality refined, high viscosity mineral oils
compounded with a small percentage of fatty oils. They are used, primarily,
for the lubrication of steam cylinders working under high temperature, high
pressure conditions, where low carbon formation and ‘steam washing’
are important considerations. They atomise more easily and with steam
of moderate superheat and produce more tenacious lubricating films than
‘straight’ grades of the same viscosity.
