Proportional pressure and flow control valves that deliver precise output in challenging applications
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.
Proportional flow control valves function with a variety of media, including air, neutral gases, steam, water, and aggressive fluids. Their responsive, precise function and rapid response can adjust for a wide variety of changes throughout the application control chain, making the entire production process more efficient. Optimized flow control improves process and batch quality in highly demanding applications.
ASCO™ 290 Angle-Body Piston Valve
The ASCO 290 angle-body piston solenoid valve can handle aggressive fluids such as steam, hot water, solvents, and light slurries.
ASCO™ 209 Proportional Solenoid Valve
The ASCO 209 solenoid valve is designed to proportionally control the flow of air, inert gases, and liquids with high repeatability.
ASCO™ 202 Preciflow Proportional Valve
The ASCO 202 Preciflow solenoid valves are designed to proportionally control the flow of air and gases in medical equipment and analytical instrumentation.
ASCO™ 607 FlowtronicD Proportional Valve
The ASCO 607 FlowtronicD proportional valve with pressure sensor units is designed for applications with continually varying flow requirements.
Proportional pressure control valves, including directly or indirectly controlled and pilot valves, are essential to control and compensation for dynamic variations in the control chain. They maintain pressure below the upper limit of safe operation and typically must provide short response times and adjustable parameters to meet specific requirements of media or application, and low energy consumption to meet efficiency and sustainability goals.

AVENTICS 608 SentronicD Proportional Regulator
The AVENTICS 608 SentronicD 3-way, direct-operated proportional pressure regulator valve with digital control has fast response times and high sensitivity.
Emerson's high-pressure regulators are the go-to solution for high pressure control up to 20,000 psi (1378 bar). Pairing a regulator with the TESCOM electropneumatic controller or the AVENTICS proportional valve enables precise remote control and closed-loop feedback. This eliminates common issues such as droop or creep due to varying inlet pressure conditions. The included software enhances system intelligence with valuable data and user-friendly tools for troubleshooting.
