Discover our new proportional valve
The ASCO Series 209 proportional valves offer superior precision, flow and power consumption for medical devices, hydrogen fuel pumps, food equipment and more
A proportional valve provides control in applications where output pressure or flow varies or is based on a dynamic set point. They provide control over air, gases, or water through rapid, highly precise response and help streamline applications while delivering repeatable control and desired output. Emerson’s wide selection of low or high-flow, direct acting, piloted, open or closed-loop proportional valves and regulators deliver ultra-reliable and precise performance.
Emerson's Arthur Gosling explains why proportional valves are key elements to make your machines and processes smarter and more reliable. Their flexibility enables you to easily adjust the settings on your machines, for continuous improvement over the lifetime of your equipment.
The SENTRONIC HD is a highly accurate, electronic proportional pressure control valve for sophisticated applications in pneumatic control engineering. By highly accurate, we mean a control deviation of less than 0.25 %. The SENTRONIC HD enables precise control of pressure, flow rate, power, speed, distance or angular positions.
Proportional control is an important part of laboratory and life science applications.
Advanced proportional controllers provide analytical insights into dozens of applications.
