The Honeywell VRN2H4PXA202 is a dynamic pressure regulated control valve assembly. It integrates flow and temperature control in one unit, making it suitable for hydronic systems. This valve helps maintain temperature during pressure fluctuations in the piping.
Compatible with Honeywell standard actuators.
Available sizes range from one-half inch to three inches with female NPT connections.
Designed for hot or chilled water with glycol solutions up to fifty percent.
Product Highlights
The valve features a differential pressure regulator to ensure a constant pressure drop across the valve seat.
