Flow rate regulator DN 15 with glass measurement zone, 2 fill/drain connections with ball shut-off valves - flow rate regulation

The Barberi® flow rate balancing valves of this series are used to read and balance the system flow rate. They are normally used in closed circuits of forced thermal solar and standard heating systems. These products are made of a flow rate reading area, a ball shut-off valve to regulate the flow rate, two connections to fill and drain the system with built-in ball shut-off valves, pump connection. The features of this product are the reading area in transparent glass, which allows the reading during time, and the brass indicator which maintains the geometry even when temperatures vary.
