The Honeywell VRN2EMPX7100 is a pressure independent control valve used in hydronic systems for both flow and temperature control. This valve adjusts flow automatically to keep temperature steady, accommodating any fluctuations in pressure. It includes a pressure control cartridge that merges flow balance and control into one unit. The design is suitable for hot or chilled water, even with a glycol solution content of up to fifty percent.
NPT connections ensure compatibility.
Ideal for 2-way configurations.
Developed for a flow rate of ten GPM.
Product Highlights
Reliable pressure regulation in diverse systems.
