The Honeywell VRN2G2SX9202 is a pressure independent control valve assembly for closed-loop HVAC systems. It provides a consistent flow of hot or chilled water, handling up to fifty percent glycol solutions, despite changes in pressure.
Maintains constant flow in HVAC systems despite pressure variations.
Features a 2-way ball valve design with NPT connections.
Compatible with Honeywell direct coupled actuators.
Product Highlights
This valve includes a differential pressure regulator to ensure fluid flow remains constant, making it suitable for various HVAC applications.
