Valves regulate the passage of liquid and gaseous substances. They are an integral part in the household as well as in many industrial areas. Factors that have to be considered when choosing the appropriate lubricant are, among others, good compatibility with sealants and the influence of humidity or chemically aggressive media. Especially if the incidental contact with food cannot be avoided e. g. during conveying drinking water, bottling of juices and refreshments or alcoholic beverages, such as beer, wine or spirits, exclusively physiologically inert, odour and taste neutral lubricants should be applied. For the application in valves LUBCON offers media resistant special lubricants that have good lubricating properties at high and low temperatures. They are compatible with EPDM (Ethylene Propylene Dien Monomer), NBR (Nitril Butadien Rubber), FPM (Fluorinated Propylene Monomer) as well as rubber seals. The lubricants are regularly tested and certified by NSF, KTW, ACS, and/or MPI and approved by the BAM (German Federal Institute for Materials Research and Testing)for the use in fittings and other applications in gaseous oxygen.
