The Honeywell VRN2H5SX7200 is a pressure independent control valve assembly designed for closed-loop HVAC systems. It maintains consistent fluid flow of hot or chilled water, even with up to fifty percent glycol solutions.
Maintains constant flow in HVAC systems.
Features a differential pressure regulator.
Suitable for water or glycol solutions up to 50%.
Product Highlights
This valve integrates flow and temperature control functions. It consists of a 2-way ball valve with NPT connections and incorporates stainless steel trim for durability. The valve's differential pressure regulation ensures consistent fluid flow regardless of supply pressure variations. It is highly efficient in maintaining desired water temperatures in various HVAC applications.
