The Honeywell VRN2HTSX8100 is a pressure-regulated control valve assembly designed for efficient flow and temperature regulation in hydronic systems. This valve automatically adjusts flow to maintain consistent temperature even when piping pressures change. It includes a built-in pressure control cartridge for precise flow balancing and is compatible with Honeywell actuators.
NPT connections for easy installation
Works with hot or chilled water up to 50% glycol solutions
Features a differential pressure regulator for stable pressure drop
Product Highlights
This valve is essential for optimizing performance in heating and cooling applications.
