FIELD: agriculture.

SUBSTANCE: group of inventions relates to the field of agriculture. The valve block contains a primary line and a secondary line. An electronically controlled pilot valve is located between the primary line and the secondary lines. The valve position can be held and/or changed by a retaining magnet. In series connection with the pilot valve, there is a passive bypass valve between the primary line and the secondary line. The valve system of agricultural spraying contains the valve block described above. There is a control unit with control logic that, from the electrical loading of the retaining magnet, reveals at least one characteristic value that at least correlates with the flow rate and/or the degree of clogging of the agricultural spraying valve block, secondary line and/or outlet nozzle.

EFFECT: operational reliability, anti-drip protection, the possibility of clogging detection and/or registration of flow rate is provided.
