The Honeywell VRN2H3SX8200 is a pressure independent control valve designed for efficient flow and temperature control. This valve features a 3-inch NPT connection and is built for on/off control with a fail-safe closed position. It is effective in maintaining temperature by automatically managing flow in hydronic systems, compensating for pressure changes.
Compatible with water and glycol solutions.
Constructed with a stainless steel trim for durability.
Can handle maximum differential pressure ranging from 1 gpm to 95 gpm.
Product Highlights
Reliable pressure independent valve suitable for various applications in commercial and residential heating systems.
