Honeywell VRN2EQSX4002 Dynamic Pressure Regulated Control Valve Assembly

Product Description

The Honeywell VRN Series valve, MPN VRN2EQSX4002, integrates flow and temperature control in a single assembly. This two-way valve automatically regulates flow in hydronic systems to maintain temperature during pressure fluctuations. It features an integrated pressure control cartridge that ensures flow balancing and control. The valve is suitable for water or glycol solutions up to fifty percent.

• Features a differential pressure regulator for a constant pressure drop.
• Offers equal percentage flow characteristic using a patented flow control ball insert.
• Includes a removable, manual operating handle for control during installation or power failure.

Product Highlights

This valve is ideal for applications requiring precise flow and temperature control in heating systems.
