About the Honeywell VRN2AD3D2A

The Honeywell VRN2AD3D2A Fltg Picv 1/2 In Npt 2 0 Gpm w/tp is designed to keep the necessary flow pace through the valve by controlling the pressure drop across the control valve seat. The actuator adjusts the control valve portion of the valves to the requisite flow based on heating or cooling load requirements. It prevents an overflow or underflow when conventional two-way valves in multi-zone systems open or close. The Honeywell VRN2AD3D2A/M 1/2 in. f-NPT Floating Pressure Independent Control Valve is independent of supply pressure. Its actuator motion ends when the room controller is in stability and the valve is now set at finest flow. The built-in diaphragm controller balances for the adjustment if system head pressure changes which results to preserving the flow required by the control system without using the actuator. Honeywell VRN2AD3D2A/M 1/2 in. f-NPT Floating Pressure Independent Control Valve balances the structure at every point over the range of the control valve within 5% precision at published pressure ratings. The use of Honeywell VRN will result to constant comfort, greater than before energy efficiency and increased actuator life.
