Honeywell VRN2G8SX8100 Pressure Independent Control Valve

Product Description

The Honeywell VRN2G8SX8100 is a pressure-independent control valve designed for hydronic systems. This valve efficiently manages flow and temperature, ensuring consistent performance during pressure changes. The unit includes an integrated pressure control cartridge that facilitates balanced flow and temperature control.

• Features a differential pressure regulator to maintain a constant pressure drop across the valve.
• Utilizes a patented flow control ball insert for equal percentage flow characteristics.
• Compatible with hot or chilled water, suitable for up to 50% glycol solutions.

Product Highlights

This control valve is essential for HVAC applications where precise flow management is required.
