The Honeywell VRN2E2SX7102 pressure regulated control valve is designed for efficient flow and temperature control within hydronic systems. This unit automatically adjusts flow to maintain optimal temperature levels despite pressure changes. It includes a built-in pressure control cartridge to ensure effective flow balancing.
Threaded connection sizes range from one half inch to three inches FNPT.
Compatible with hot or chilled water, including solutions with up to fifty percent glycol.
Features a differential pressure regulator for constant pressure maintenance.
Product Highlights
Ideal for applications requiring precise control over fluid flow and maintaining temperature in heating or cooling systems.
