The Honeywell VRN2H4SXD000 is a pressure independent control valve assembly tailored for HVAC systems. This valve maintains steady flow of hot or chilled water in closed-loop systems while adapting to pressure changes. Its design incorporates an effective pressure control cartridge, ensuring consistent flow balancing and control. The valve is compatible with Honeywell direct coupled actuators, making it a versatile choice for many applications.
Maintains constant flow regardless of pressure fluctuations.
Features a differential pressure regulator.
Compatible with Honeywell direct coupled actuators.
