As a manufacturer of pneumatic systems you expect valves to operate smoothly at both high and low temperatures. You therefore need a grease that is compatible with the materials used and also has a wide service temperature range. Klüberbeta RM 47-291 is a special grease enabling smooth component operation at low temperature and offering high thermal stability. It is based on silicone oils and contains a lithium soap thickener. Due to its specific consistency, it shows good backflow behaviour into the lubrication gap.
Its shows notably good compatibility with many elastomers (except silicone rubber) and plastics.
