Emerson ASCO™ Series 209 proportional flow control valves

Emerson has introduced the ASCO™ Series 209 proportional flow control valves, which offer high standards of precision, pressure ratings, flow characteristics and energy efficiency 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 the heating, ventilation and air conditioning (HVAC), as well as medical equipment, food and beverage industries, Emerson said.

Emerson noted accuracy, response time and repeatability are critical in high-precision flow control applications, such as controlling water flow in cooling systems. 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.

“We designed the ASCO Series 209 valves to deliver the highest level of performance in a small footprint, giving our customers the flexibility and confidence to engineer products that drive innovation, foster sustainability, lower costs and improve people’s lives,” said Shivam Chauhan, Commercial Product Marketing Manager, Europe, the Middle East and Africa at Emerson’s Discrete Automation Business.

The low power consumption and fast response time (less than or equal to 15 milliseconds) of Series 209 optimizes system performance and efficiency. An improved internal design prevents metal-on-metal contact that causes clicking, which allows valves to operate at extremely low sound levels that are crucial for occupant comfort and well-being.

Series 209 valves meet global approvals, including Underwriters’ Laboratories (UL), United Kingdom Conformity Assessed (UKCA) and European Conformity (CE) and include a range of options that tailor valves for specific applications, Emerson said.
