Honeywell VRN2F4SX8100 Pressure Independent Control Valve

Product Description

The Honeywell VRN2F4SX8100 is a pressure-independent control valve designed for efficient flow and temperature management in hydronic systems. This valve automatically adjusts flow to maintain desired temperature levels during pressure changes. It features a built-in pressure control cartridge for effective flow balancing, suitable for both hot and chilled water applications with up to fifty percent glycol solutions.

• Sizes range from one half to three inches with female NPT connections.
• Engineered for hot or chilled water systems with up to fifty percent glycol.
• Includes a differential pressure regulator for consistent pressure drop across the valve seat.

Product Highlights

This control valve is ideal for HVAC applications needing precise temperature control and flow regulation.
