Price Supply Venturi Valves (VV), controlled by the Laboratory Space Controller (LSC) provide make-up air to the laboratory space for the fume hoods and all other exhaust devices to ensure proper pressure relationships are maintained. In addition the supply venturi valves will deliver cooling airflow to meet that space loads as well as maintaining the ventilation requirements. 

Venturi Valves (VV) are mechanically pressure independent control valves designed specifically for room pressure and fume hood control applications. The highly engineered internal cone assembly ensures the valve will respond to changes in duct static pressure in less than one second, while turndown ratios in excess of 16:1 serve to maximize energy savings in unoccupied or minimum flow set-points.
