摘要

The valve arrangement comprises two flow regulating valves (1,2) and a throttle valve (3). The first valve (1) has a pressure balance (4) and an adjustable measuring throttle (5) in series between a connection (6) for the constant pressure source (7) and the outlet (8) of the flow regulating valve.
