Proportional Valves

Achieve smooth, accurate control with our high-performance proportional valves. Unlike standard on/off valves, these valves provide variable flow or pressure adjustment, allowing for precise system tuning and improved efficiency. Our selection includes proportional pressure control valves, proportional flow control valves, and electro-hydraulic designs, available in a wide range of sizes, materials, and control signal options. Ideal for automation, robotics, machine tools, injection molding, and industrial process systems, proportional valves deliver reliable performance in applications where precision matters. With rugged construction, fast response times, and trusted-brand reliability, our proportional valves provide long service life, efficient operation, and precise control, making them an essential choice for advanced system design.

The ASCO Series 202, also known as 8202, direct-operated Posiflow solenoid valves are designed to control the flow of air, liquids 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.
