PP-H metering ball valve PROGEF Type 523 Pro PN10

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 523 Pro metering ball valve is engineered from high-grade beta polypropylene homopolymer (beta-PP-H) for high-precision micro-dosing and linear flow regulation in demanding chemical and industrial processing systems. Designed specifically for low-flow fluid control where conventional ball valves lack resolution, the Type 523 Pro features a specialized metering ball geometry coupled with an extended 180 degrees operating angle. An integrated graduated scale on the indexing handle provides fine visual positioning, enabling precise, repeatable flow rate settings across varied process environments.

Manufactured with a true double union construction, the valve permits straightforward radial installation and non-destructive maintenance without dismantling adjacent pipe segments. The internal ball seating mechanism utilizes chemically inert PTFE seats with dynamic backing seals that compensate for thermal fluctuation and mechanical wear over prolonged service intervals. Process integrity is secured through high-performance EPDM or FKM elastomeric gaskets. The robust valve body incorporates factory-integrated M6 stainless steel threaded inserts on the base, allowing rigid structural anchoring to pipe clips or mounting brackets without distorting the internal flow bore.

The isotactic polypropylene homopolymer construction guarantees exceptional chemical resistance against concentrated acids, alkaline solutions, demineralized water, and aggressive process reagents up to PN10 nominal pressure ratings at 20 degrees Celsius. Socket fusion metric end connections ensure seamless, leak-tight integration into standard PROGEF piping networks, with standardized face-to-face z-lengths ensuring full interchangeability with legacy Type 523 series assemblies. BigWeld supplies authentic Georg Fischer industrial flow control solutions engineered for process safety, consistent hydraulic repeatability, and long service life in water treatment, chemical dosing, and laboratory applications.
