The Honeywell VRN Series valve, MPN VRN2ESSXC000, is a pressure-regulated control valve assembly that integrates flow and temperature control. This valve automatically manages flow in hydronic systems to maintain temperature during fluctuations. It includes an integrated pressure control cartridge to facilitate flow balancing and control.
Designed for threaded connections, suitable for sizes from one-half inch to three inches FNPT.
Compatible with Honeywell 44 in-lb direct-coupled actuators.
Suitable for water or glycol solutions up to fifty percent.
