The Honeywell VRN2AFPX7100 is a pressure independent control valve and actuator assembly. This two-way valve is used in closed-loop HVAC systems to maintain a constant flow of hot or chilled water, mixed with up to 50% glycol.
Maintains constant flow regardless of pressure fluctuations.
Features a differential pressure regulator.
Designed for systems using hot or chilled water with glycol solutions.
Product Highlights
This valve is equipped with an integrated pressure control cartridge for effective flow balancing and temperature management.
