The Honeywell VRN2HU3D2D 3 Inch Threaded Pressure Independent Control Valve 45 GPM with Top Plate. This valve is a pressure regulating control valve. It is a certified product manufactured by Honeywell. It is designed to keep the necessary flow rate through the valve by controlling the pressure drop across the control valve seat. It prevents an overflow or underflow when conventional two-way valves in multi-zone systems open or close. The actuator adjusts the control valve to the requisite flow based on heating or cooling load requirements. The Honeywell VRN2HU3D2D 3 Inch Threaded Pressure Independent Control Valve 45 GPM with Top Plate works independent of supply pressure. If system head pressure changes, the built-in diaphragm controller accounts for the changes which results in preserving the flow required by the control system without using the actuator, while maintaining 5% precision at published pressure ratings. This Honeywell VRN2HU3D2D 3 Inch Threaded Pressure Independent Control Valve 45 GPM with Top Plate is recommended to improve energy efficiency while reducing your maintenance costs of closed loop heating systems and various ventilating and air conditioning systems as well.
