The Honeywell VRN2DMSX7100 is a dynamic pressure regulated control valve assembly designed for hydronic systems. It automatically adjusts flow to maintain temperature amid fluctuating pipeline pressures. This valve features an integrated pressure control cartridge for efficient flow balancing and control.
Includes differential pressure regulator for constant pressure maintenance.
Utilizes patented flow control ball insert for equal percentage flow.
Equipped with an upstream test port for easy venting or pressure gauge connection.
Product Highlights
This valve is compatible with standard Honeywell actuators and available in sizes from half inch to three inches FNPT.
