These mixing valves with metering can be consolidated into groups for multiple lubrication points. In this case, the compressed air must be fed separately to each mixing valve. Metering is performed by an integrated single-line metering device. You can select between 0,03; 0,06 and 0,1 cm3/cycle. The lubricant supply connection has a counterbore for a solderless tube union for lines with ∅4 mm. The connection for compressed air is either G1/2 or G3/4 depending on the design.
