Fluid control valve for a heating and or cooling system is compact and provides reliable pressure measurement for pre-setting of the control flow rate

摘要

Fluid valve for a heating and or cooling system has a housing (1) with supply (2) and outlet (3) connections with a connection (4) for the control valve insert (4, 5) between them. A pre-adjustment device (8) forms part of the valve insert (5) and a choke point (9) at least partially encompasses the control valve seat (7). Pressure measurement channels (10, 11) open out in pressure measurement connections (12, 13).
