The Honeywell VRN2H8PXA202 is a pressure independent control valve assembly designed for hydronic systems. This valve regulates flow and temperature automatically, ensuring efficient operation even when pressures fluctuate. It is a three-inch, two-way valve equipped with NPT connections, functioning on twenty-four VAC, and includes one auxiliary switch. This valve operates with a fail-safe closed configuration and supports a flow rate of eighty-five GPM.
2-way ball valve with straight-through flow and full port
Compatible with water or glycol solutions up to fifty percent
Includes a pressure regulator with a hydrogenated acrylonitrile-butadiene rubber diaphragm
Product Highlights
The Honeywell VRN2H8PXA202 is essential for maintaining control in hydronic systems, balancing flow to achieve stable temperature settings.
