The Honeywell VRN Series valve, MPN VRN2CNPX4000, is a pressure-regulated control valve assembly designed for effective flow and temperature control in hydronic systems. This valve automatically adjusts the flow to maintain the desired temperature, even when the pressures in the piping fluctuate. It includes a built-in pressure control cartridge, enabling precise flow balancing and regulation.
1-inch FNPT connections for easy installation.
Compatible with hot or chilled water systems, including up to fifty percent glycol solutions.
Incorporates a differential pressure regulator for efficient flow management.
