The Honeywell VRN2CDPXA102 Pressure Independent Control Valve integrates flow and temperature control in various hydronic systems. This valve is essential for maintaining temperature stability as it adjusts to changes in piping pressure. Featuring a built-in pressure control cartridge, it balances flow effectively and is compatible with Honeywell direct-coupled actuators.
Sizes range from one half to three inches with female NPT connections.
Compatible with hot or chilled water, and can handle up to fifty percent glycol solutions.
Includes a differential pressure regulator to maintain a constant pressure drop across the valve seat.
Product Highlights
This valve is engineered for reliable performance in temperature control applications within hydronic systems.
