Ball Valve 523 Pro

The Ball Valve 523 Pro is a precise metering ball valve. The linear flow characteristics and the circular scale permit the sampling of small amounts of media with great accuracy. Additionally, the sophisticated ball design precludes sudden flow increases while the lockable lever adds another layer of safety. The 523 Pro is also available in vertical execution, increasing the fields of applications even further. The wide range of materials, dimensions, and end connections make the Ball Valve 523 Pro the perfect solution for various applications, such as Water Treatment, the Chemical Process Industry, Microelectronics, or Marine applications.
