Single-line metering valves of SKIE series are used in distribution manifolds of SRK series and supplied in a seven size series assigned by a lubricant nominal dose from 0.015 to 0.30 cm³/stroke, for working pressures in the range of 10 to 50 bar. Single-line metering valves of SKIE series are also supplied with push-on fittings for quick installation of piping. Metering valves of SMIE series are set directly into the lubricated point and, as well as single-line metering valves of SKIE series, supplied in the same size series with the same working parameters. Lubrication system distribution is created by the means of distribution manifolds SRK or by linking fittings or their mutual combination.
