FLOWMATIC® - Pressure Independent Control Valve - NA Market

The FLOWMATIC® pressure independent control valve (PICV) combines an automatic differential pressure regulator and a control valve with optional actuator. The PICV automatically adjusts flow rate and keeps it constant under changing circuit differential pressure conditions where it is installed.
Flow rate is adjusted either:
•manually on the automatic differential pressure regulator, to restrict the maximum value, or
•automatically by the control valve in utilizing a separately purchased and field installed proportional (0–10 V) or ON/OFF actuator.
The (PICV) is supplied complete with upstream and downstream pressure test ports for measuring operating conditions.
The FLOWMATIC PICV is designed for use in hydronic heating and cooling systems and has tight shutoff to minimize energy loss.
