Emerson (St. Louis, MO) has introduced the ASCO Series 209 proportional flow control valves, which offer the highest standards of precision, pressure ratings, flow characteristics and energy efficiency available in a purpose-built, compact architecture. With this combination of size and performance, Series 209 valves allow users to precisely regulate the flow of fluid in a wide range of devices that require exacting performance, like those found in food and beverage.
Accuracy, response time and repeatability are critical in high-precision flow control applications. Series 209 valves have low hysteresis (less than or equal to 5%), excellent repeatability (less than or equal to 1%) and high sensitivity (less than or equal to 0.2%) that contribute to their precision.
The low power consumption and fast response time (less than or equal to 15 milliseconds) of Series 209 can extend battery life in devices powered by them and optimize system performance and efficiency.
