The Honeywell VRN Series valve, MPN VRN2E2SX7100, is designed for pressure-regulated control in hydronic systems. This valve maintains consistent temperature by automatically controlling the flow, even during pressure changes. It integrates a pressure control cartridge for effective flow balancing. The valve is compatible with Honeywell direct-coupled actuators and comes in threaded sizes from one-half inch to three inches FNPT.
Features a differential pressure regulator for constant pressure drop.
Offers equal percentage flow characteristic using a patented flow control ball insert.
Suitable for hot or chilled water with up to fifty percent glycol solutions.
Product Highlights
This valve provides reliable flow control and is essential for maintaining system efficiency.
