The Honeywell VRN2E5PX7200 is a pressure-independent control valve designed for efficiency in hydronic systems. This valve ensures consistent flow and temperature control during pressure changes. The integrated pressure control cartridge allows for precise flow balancing and is suitable for hot water, chilled water, and glycol solutions up to fifty percent.
Sizes available from half inch to three inches with female NPT connections.
Features a differential pressure regulator that maintains a constant pressure drop across the valve seat.
Utilizes a patented flow control ball insert for equal percentage flow characteristics.
Product Highlights
The valve is efficient, maintaining flow even with varying pressures. It is tailored for both heating and cooling systems.
