ABSTRACT:
A distribution valve having a flowmeter for use in a flow pipe of a hot water heating circuit. The distribution valve has a branch line and an adjusting and measuring unit for adjusting and displaying the flow rate through the branch line with the elements being screwed into opposing threaded holes of the distribution line. The valve gap determines the flow rate through the branch line formed between a closing body and a valve seat body with the valve seat body being configured from a fixed housing section of the adjusting and measuring unit. The flow is measured with an inflow member that is displaced by fluidic forces against a spring force in a flow canal.
