The MV20x-1 and MV30x-1 built in block design and contain up to eight secondary line connections. The lubricant metering is selectable in a range of 0,01–0,16 cm3 for each lubrication point. Secondary line connections which are not needed can be plugged. This involves screwing an appropriate metering screw for zero metering into the mixing valves.
The MV20x-1 design contains an air adjustment screw for setting the quantity of compressed air. The quantity of compressed air cannot be adjusted on the MV30x-1 design. The secondary line connections on both designs are available with SKF plug connectors or fittings for solderless tube unions for tube ∅4 mm.
Another oil and air mixing valve must be provided if more than eight lubrication points will be supplied. In this case, the compressed air must be fed separately to each mixing valve.
