Emerson announced the introduction of the 209 Series ASCOTM proportional valve for flow applications. These valves meet the highest standards for accuracy, pressure ratings, flow characteristics and energy efficiency in a purpose-built, compact design. Users can thus precisely control the flow of a medium in a wide range of devices. These include products in diverse industries such as medical, food and beverage, and heating, ventilation and air conditioning (HVAC) that require operation with high accuracy.
Accuracy, response time and repeatability are critical factors in applications for high-precision flow control, such as controlling tool speed in dental offices, steam flow in coffee machines, water flow in cooling systems and hydrogen flow in fuel cells. 209 Series valves feature low hysteresis (less than or equal to 5%), high repeatability (less than or equal to 1%), and high sensitivity (less than or equal to 0.2%), which contribute to valve accuracy.
