The Honeywell VRN2CHPXA100 is a pressure-independent control valve designed for efficient flow management in hydronic systems. This valve automatically regulates flow to maintain consistent temperature levels, even during fluctuations in piping pressures. It features an integrated pressure control cartridge for flow balancing. Designed for water or glycol solutions up to fifty percent, the valve connects with threaded internal NPT fittings, accommodating sizes from one-half inch to three inches.
Compatible with Honeywell direct-coupled actuators.
Maintains a constant pressure drop across the valve seat.
Utilizes a patented flow control insert for equal percentage flow characteristics.
Product Highlights
This valve offers dynamic regulation of flow and is suitable for both commercial and residential applications.
