The Honeywell VRN2EUSXB200 is a pressure-independent control valve assembly designed to manage flow and temperature in hydronic systems. This valve automatically adjusts flow to maintain optimal temperature levels even during pressure changes. It integrates a pressure control cartridge that allows for precise flow balancing.
Available in sizes from half an inch to three inches with female NPT connections.
Compatible with hot or chilled water, including up to fifty percent glycol mixtures.
Features a differential pressure regulator that ensures a steady pressure drop.
Product Highlights
This valve is suitable for various hydronic applications and is engineered for efficiency and durability.
