The Honeywell VRN2H4SX9200 is a pressure independent control valve assembly designed for hydronic systems. This three-inch NPT, two-way valve maintains consistent temperature by controlling flow as piping pressures change. It features a stainless steel trim and an integrated pressure control cartridge, allowing for effective flow balancing.
Operates efficiently in flow rates up to sixty-five gallons per minute.
Compatible with water and glycol solutions up to fifty percent.
Normal operation on 100-250 VAC.
Product Highlights
The valve is normally closed and includes one auxiliary switch for enhanced control.
