The Honeywell VRN Series VRN2CDPX6202 is a pressure-independent control valve that regulates flow and temperature in hydronic systems. This assembly ensures consistent temperature control even with pressure changes. It features a built-in pressure control cartridge that balances flow effectively. The valve has 1 inch FNPT connections and is compatible with Honeywell direct-coupled actuators, supporting both hot and chilled water up to fifty percent glycol.
Sizes range from one half to three inches with internal NPT connections.
The differential pressure regulator keeps a constant pressure drop across the valve seat.
Includes a removable manual operating handle for operation when power is unavailable.
