PP-H Pressure Reducing Valve Type V82 d75-110

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type V82 pressure reducing valve regulates and stabilizes downstream pipeline pressure across industrial thermoplastic piping systems. Manufactured from high-grade isotactic polypropylene homopolymer (beta-PP-H) with robust EPDM elastomer seals, this valve utilizes an internal spring-loaded diaphragm mechanism to continuously balance differential pressure forces. It automatically reduces higher or fluctuating upstream line pressures down to a constant, pre-selected downstream working value, safeguarding downstream equipment, measurement instrumentation, and process pipework against overpressurization and pressure surges.

Engineered specifically for demanding media distribution, water treatment, wastewater processing, and chemical processing networks, the PROGEF Type V82 combines high mechanical strength, chemical resistance, and thermal endurance. The beta-PP-H body provides outstanding resistance to non-oxidizing acids, bases, and industrial salt solutions at operating temperatures up to 80 degrees Celsius. The internal EPDM diaphragm and auxiliary seals ensure leak-tight sealing integrity and smooth regulation dynamics without mechanical stick-slip behavior across prolonged industrial service cycles.

Featuring integrated metric spigots, the Type V82 d75-110 valve is designed for direct pipeline integration using butt fusion or electrofusion jointing. The unit includes a built-in manometer port that enables direct mounting of a pressure gauge for immediate verification and precise calibration of downstream pressure settings. The spring assembly allows convenient field adjustment of the target setpoint, maintaining steady downstream hydraulics even under substantial supply pressure variations or fluctuating consumption rates.
