The Honeywell VRN2HQSX8200 is designed for HVAC systems as a pressure independent control valve assembly. It keeps a steady flow of hot or chilled water, capable of handling up to 50% glycol solutions in closed-loop configurations. This valve includes an integrated pressure control cartridge for maintaining flow balance and is compatible with Honeywell direct coupled actuators.
Keeps constant flow despite pressure changes.
Incorporates a 2-way ball valve body with NPT connections.
Applicable for hot or chilled water with up to 50% glycol solutions.
Product Highlights
Ideal for consistent water flow management in HVAC applications.
