Each mixing valve is connected to a secondary line. Mixing valves can be combined into groups for multiple lubrication points. Oil supply and metering are accomplished by a single-line metering device connected to the mixing valve and used in a centralized intermittent lubrication system. Compressed air supplied to the mixing valve moves the lubricant into the secondary line and to the lubrication point. The metered volume depends on the number of lubrication cycles in intermittent lubrication systems and the selected volume.

The lubricant supply connection has a recess for a solderless connection for 4 mm diameter tubing. The compressed air connection is G½ or G1, depending on the design. Each additional lubrication point requires an additional mixing valve. In this case, compressed air is supplied separately to each mixing valve.
