The Honeywell VRN2G2PX4000 is a pressure independent control valve designed to help manage flow in hydronic systems. This two-way valve features a two and one half inch NPT connection and supports a flow rate of fifty five gallons per minute. It is suitable for hot or chilled water applications, including solutions with up to fifty percent glycol. The valve incorporates a pressure control cartridge to maintain the desired temperature by adjusting flow automatically, which is crucial when piping pressures change. The valve also supports floating and two-position control signals and includes fail-in-place functionality.
Two and one half inch NPT connection.
Fifty five GPM flow rate.
Operates on twenty four VAC.
