Caleffi Introduces FLOWMATIC Pressure Independent Control Valve

Caleffi North America introduces the 145 Series FLOWMATIC pressure independent control valve. Available as a standalone valve or as the 149 Series FLOWMATIC Express, pre-assembled terminal unit coil kit. The valves combine an automatic differential pressure regulator and a control valve with an optional actuator.

With a control signal input, the valve automatically adjusts the flowrate and keeps it constant under changing circuit differential pressure conditions. It is designed for hydronic systems and is supplied complete with pressure test ports for measuring operating conditions. The valve is available in ½, ¾ and 1 inch valve body sizes with sweat, press and FNPT union tailpieces.
