The Honeywell VRN Series valve, MPN VRN2CDPXA100, integrates flow and temperature control in a single assembly. This pressure-regulated control valve automatically adjusts flow in hydronic systems to maintain consistent temperature during pressure changes. It includes a built-in pressure control cartridge for effective flow balancing and regulation.
Features a differential pressure regulator for constant pressure drop.
Offers equal percentage flow characteristics using a patented flow control ball insert.
Includes a removable manual operating handle, providing control during installation or power outages.
Product Highlights
Utilized for systems involving water or glycol solutions, accommodating up to fifty percent concentrate.
