The 523 Pro Series ball valves are precise metering ball valves excellent for water treatment, chemical processes, microelectronics, or marine applications. The linear flow characteristics and the circular scale permit the sampling of small amounts of media with great accuracy. The sophisticated ball design precludes sudden flow increases, while the ergonomically designed, lockable lever adds another layer of safety and ease of use. A manual spring return unit ("dead man's lever") ensures the valve automatically closes when released. This reliable, compact, cost-effective solution ensures end-to-end process safety and quickly eliminates the potential for far-reaching risks.
