The Honeywell VRN2H3SXA202 is a dynamic pressure regulated control valve assembly suitable for hydronic systems. This valve automatically manages flow to maintain temperature even when there are variations in piping pressures. It features a pressure control cartridge that balances flow effectively. The valve accommodates water and glycol solutions with a concentration of up to fifty percent.
Sizes available from one half to three inches with female NPT connections.
Suitable for controlling both hot and chilled water systems.
Includes a differential pressure regulator to ensure a consistent pressure drop across the valve seat.
