Honeywell VRN2H3SX4000 Pressure Independent Control Valve Assembly

Product Description

The Honeywell VRN2H3SX4000 is a pressure independent control valve assembly designed for HVAC systems. This valve regulates the flow of hot or chilled water, including solutions with up to fifty percent glycol, within closed-loop systems regardless of pressure changes. It integrates flow and temperature management, enabling automatic adjustment in hydronic circuits to regulate temperature effectively.

• NPT connections available in sizes from one-half to three inches.
• Compatible with up to fifty percent glycol solutions for both hot and chilled water.
• Allows for regulated flow rates from one to ninety-five gallons per minute.

Product Highlights

This valve includes a differential pressure regulator that removes the need for system balancing, contributing to efficient HVAC operations.
