The Honeywell VRN Series valve, MPN VRN2BBPX4002, controls flow and temperature in hydronic systems. This assembly automatically adjusts flow to maintain temperature during pressure changes. It integrates a pressure control cartridge for effective flow balancing and control.
Features a three-fourth inch NPT connection.
Designed for two-way operation with a flow rate of one gallon per minute.
Operates using a twenty-four VAC supply voltage.
Product Highlights
Efficiently manages hot or chilled water with the capability for up to fifty percent glycol solutions.
