HONEYWELL VRN2AFSA1000 Pressure Independent Control Valve Assembly

Product Description

The Honeywell VRN2AFSA1000 is a pressure independent control valve assembly designed for hydronic systems. This assembly integrates both flow and temperature control. It ensures a constant flow of hot or chilled water, even when pressure fluctuations occur. This makes it effective in various applications. The assembly includes a differential pressure regulator and pairs with Honeywell direct coupled actuators for optimal performance.

• Maintains constant flow regardless of pressure fluctuations.
• Features a differential pressure regulator.
• Suitable for water or glycol solutions up to fifty percent.

Product Highlights

This valve assembly delivers reliable performance in hydronic systems and can efficiently handle temperature variations.
