The Honeywell VRN2H4SX9100 is a pressure independent control valve designed for efficient flow management. This three-inch NPT, two-way valve provides reliable operation in hydronic systems by maintaining temperature through precise flow control despite pressure changes. Its durable stainless steel trim and DCA profile enhance its performance.
Features a two-way ball valve that supports straight-through flow with a full port and patented flow control insert.
Suitable for use with water or glycol solutions up to fifty percent concentration.
Equipped with a differential pressure regulator, ensuring a constant pressure drop across the valve seat.
Product Highlights
This valve is essential for maintaining optimal system efficiency and temperature regulation in hydronic applications.
