Proportional Valves

ASCO Series 290 Proportional Valves with Positioner or with motor is suitable for use in process and industrial applications where a robust valve and precise flow control are required. It can be used in applications like water treatment, pharmaceutical, petrochemical and food & beverage. Angle seat valve body is designed for aggressive fluids like light slurries, viscous media, sterilization, and steam. Series 290 proportional valves provide superior safety with fail-close construction upon loss of power. LED indicators are available for valve status display.

The ASCO Series 202 Posiflow solenoid valves are designed to proportionally control the flow of air and inert gases by varying the electrical input signal to the coil. The valves large orifice sizes make them extremely versatile across multiple life science applications, including respiratory therapy, gas chromatography, blood pressure monitoring, and anesthesia delivery equipment. The 202 Series Posiflow valves compact, frictionless architecture saves valuable space in analytical and medical instrumentation.

The ASCO Numatics Series 607 FlowtronicD is a line of proportional valves with pressure sensor units and digital control electronics. Valve control loop parameters can be optimized for the application with easy-to-use FlowCom software. The Numatics Series 607 valves are designed for applications with continually varying flow requirements. Typical applications include paint coating, mixing of gases in process control, packaging and food processing, surface finishing and materials coating, burner control systems, and fuel cell technology
