Honeywell VPI Pressure Independent Control Valves and Actuators have a smart self-adjusting feature that keeps the water flow balanced at all times. These valves combine an automatic balancing valve, a pressure control valve, and a modulating control valve in one unit, making it easy to manage water flow in buildings. They are simple to select, install, and set up, saving time and money. The built-in flow regulator ensures smooth operation, and no complex calculations are needed—just choose the right valve for your flow needs.
