The Honeywell VRN2H5SXC000 is a pressure independent control valve assembly optimized for hydronic systems. This valve maintains a constant temperature by controlling flow in response to variable piping pressures. It features a built-in pressure control cartridge for effective flow balancing and compatibility with Honeywell direct-coupled actuators.
3-inch NPT connection.
70 GPM flow rate.
Operates on 24 VAC.
Product Highlights
This valve is critical for efficient regulation in heating systems, ensuring that temperature fluctuations do not affect performance.
