Ball valve Type 542 PP-H Rp PN10

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 542 ball valve is engineered from high-grade polypropylene homopolymer (beta-PP-H) to deliver reliable flow isolation across demanding industrial chemical, water treatment, and process piping systems. Designed with true double union connections and reinforced female threaded sockets conforming to ISO 7-1 (Rp), this valve allows swift radial installation, inspection, and maintenance without disassembling adjacent pipe sections. Its robust thermoplastic body provides outstanding resistance to aggressive chemical media, salts, and industrial effluents, ensuring long-term operational integrity.

Internally, the Type 542 valve incorporates pure PTFE ball seats paired with high-performance backing seals available in either EPDM or FKM elastomers. This configuration guarantees smooth manual actuation, low operating torque, and bubble-tight bidirectional shut-off. Rated for nominal operating pressures up to 10 bar (PN10) at ambient temperatures, each valve satisfies rigorous factory pressure and leakage testing in accordance with ISO 9393-2 and EN 12266 (leak rate A). The integrated ergonomic lever provides clear visual indication of valve position and precise manual throttling or shut-off control.

Engineered for a 25-year design life under nominal conditions at 20 degrees Celsius, the PROGEF Standard piping line ensures high hydrostatic strength and dimensional stability across diverse operating temperatures. The reinforced threaded socket ends provide mechanical reinforcement against piping stress and thermal cycling in rigorous industrial environments.
