Honeywell VRN2ADPX4002 Pressure Independent Control Valve Assembly

Product Description

The Honeywell VRN2ADPX4002 is a pressure independent control valve assembly designed for closed-loop HVAC systems. It maintains a constant flow of hot or chilled water, with solutions containing up to 50% glycol, ensuring optimal performance regardless of pressure changes. The valve integrates flow and temperature control, automatically regulating flow to maintain the desired temperature. Featuring an integrated pressure control cartridge, it provides excellent flow balancing and control. This valve is compatible with Honeywell direct coupled actuators.

• Maintains constant flow despite pressure variations.
• Suitable for hot or chilled water with up to 50% glycol.
• Features a pressure control cartridge for flow balancing.

Product Highlights

Ideal for efficient HVAC operation, this valve ensures reliable control of water flow across varying pressure conditions.
