The Honeywell VRN2DPPX9200 is a pressure-independent control valve assembly designed for hydronic systems. This two-way valve maintains flow and temperature through pressure fluctuations. It includes a pressure control cartridge to ensure consistent flow and balance within the system.
Features 1-1/4 inch FNPT connections.
Controls water or glycol solutions up to 50% concentration.
Designed for durability with forged brass construction.
Product Highlights
This valve is crucial for optimizing temperature control in heating and cooling systems, allowing for efficient operation even under varying pressure conditions.
