摘要

Metering valves (1) set at 90 degrees distance to each other fit together in a central metering unit (2) and have to be replaced by a dummy plug if removed. To control the valves, each valve has an electrical plug-in connector (4) that links to appropriate electronic circuitry for regulating metered amounts via an electromagnetic or an electromechanical actuator. The central metering unit has a central block (5) with a channel linking an entry hole (6) to connector points.
