Honeywell VRN2CMSX4000 Pressure Independent Control Valve Assembly

Product Description

The Honeywell VRN2CMSX4000 is a pressure-independent control valve assembly designed to ensure reliable flow and temperature control in hydronic systems. It automatically adjusts to varying piping pressures, making it suitable for both hot and chilled water applications. This valve works effectively with Honeywell direct-coupled actuators, offering a straightforward integration. The valve body is a two-way ball design, facilitating straight-through flow with a full port for minimal resistance and efficient performance.

• Flow balancing and regulation with an integrated pressure control cartridge.
• Compatible with female NPT connections ranging from half inch to three inches.
• Handles water and glycol solutions up to a fifty percent concentration.

Product Highlights

This system is ideal for maintaining temperature stability, ensuring constant control despite pressure fluctuations.
