The Honeywell VRN2BFPXB100 is a pressure independent control valve assembly designed for hydronic systems. This valve regulates flow automatically to maintain the desired temperature despite pressure changes. It accepts hot or chilled water and glycol solutions, making it versatile for different applications.
Threaded female NPT connections for easy installation.
Integrated pressure control cartridge ensures effective flow balancing.
Suitable for use with water or glycol solutions up to 50% concentration.
Product Highlights
This valve is built to integrate pressure regulation and flow control, making it ideal for temperature stability in heating and cooling systems.
