The Honeywell VRN2DQPA1000 is a pressure independent control valve with an electric actuator. This valve is designed for controlling flow in hydronic systems, effectively managing temperature by adjusting flow rates in response to changes in piping pressures. It integrates flow and temperature control and features a pressure control cartridge that ensures proper flow balancing. The valve is suitable for both hot and chilled water applications, including systems with up to fifty percent glycol solutions.
NPT connection size of one and one-fourth inches.
Maximum flow rate of twenty-five gallons per minute.
Operates at twenty-four VAC supply voltage.
