Check & Flow Valves
Pneumatic valves are essential control components for the precise regulation of flow rate, compressed-air speed and flow direction in automated systems. As a German manufacturer, eba pneumatic supplies a high-quality range of check and flow control valves that ensure reliable control of pneumatic cylinders and plant components.
Designs, operating principle and areas of application
Our valve range made of robust, nickel-plated brass covers all requirements of modern control technology. It comprises compact banjo bolt valves (DVH/DRVH) for direct cylinder mounting with 360° rotatability, versions with locknut or knurled cap to secure the setting, and push-in connections for tool-free quick assembly. The portfolio is complemented by universal block valves for integration into lines and control cabinets as well as pure check valves (RV), which prevent unwanted backflow without leakage. Designed for thread sizes from M5 to G 1/2" and an operating pressure of 0.2 to 10 bar, our pneumatic valves offer optimum control accuracy and a long service life in the temperature range from -20 °C to +80 °C.
