The Honeywell VRN2BBPA2000 is a pressure-regulated control valve assembly. This valve manages flow and temperature in hydronic circuits, maintaining consistent temperature even with pressure changes. It integrates a pressure control cartridge that aids in flow balancing. The valve design includes a two-way configuration with three-quarters of an inch NPT connections, ideal for use with Honeywell direct-coupled actuators. It effectively controls hot or chilled water and is compatible with solutions containing up to fifty percent glycol.
Features a differential pressure regulator for stable pressure drop.
Utilizes a patented flow control ball insert for equal percentage flow characteristics.
Includes a removable manual operating handle for use during installation or power outages.
Product Highlights
This valve is essential for HVAC professionals, ensuring precise control and reliability in hydronic systems.
