Honeywell VRN2AFSXB200 Pressure Independent Control Valve

Product Description

The Honeywell VRN2AFSXB200 is a pressure independent control valve suitable for hydronic systems. This valve manages flow and temperature by adjusting automatically for pressure changes. It includes a built-in pressure control cartridge to balance flow and prevent fluctuations.

• Sizes range from half inch to three inches with female NPT connections.
• Designed for both hot and chilled water with tolerances for up to fifty percent glycol.
• Incorporates a differential pressure regulator for consistent pressure management.

Product Highlights

This valve is efficient for maintaining optimal system temperatures in heating and cooling applications.
