Electric ball valve PP-H Type 127 24V PN10

  Datasheet (PDF)

Electrically actuated ball valve PROGEF Type 127 from Georg Fischer delivers automated flow isolation and process regulation across chemical distribution, industrial water treatment, and demanding fluid handling lines. Designed on the proven true double union valve architecture, this unit is manufactured from high-grade beta polypropylene homopolymer (PP-H) with metric fusion sockets for socket fusion jointing according to ISO standards. Rated for nominal operating pressures up to PN10 (10 bar at 20 degrees C), the assembly combines superior chemical resistance to aggressive media with long-term mechanical reliability across a broad operating temperature range.

The integrated EA15 electric actuator operates on a 24V AC/DC power supply and provides a factory-preset 90 degrees rotation cycle with high positioning accuracy. Encased in a flame-retardant, glass-fibre reinforced polypropylene (PP-GF) housing with IP68 environmental ingress protection, the actuator withstands corrosive ambient atmospheres and moisture. Standard internal features include an integrated heating element to prevent internal condensation, optical position indication, limit switches for electrical open/close position feedback, and an ergonomic manual emergency override mechanism for rapid manual intervention during commissioning or power failure.

Internal fluid sealing is achieved through low-friction PTFE ball seats supported by elastomeric backing rings in EPDM or FKM, ensuring dependable bidirectional shut-off, reduced operating torque, and minimal wear over extended duty cycles. The valve body features integrated stainless steel threaded inserts in the base, enabling direct anchoring to support brackets or KLIP-IT pipe clips without transferring mechanical stress to the pipeline. A specialized safety stem design with a predetermined breaking point prevents external leakage to the atmosphere under extreme mechanical overload. As an authorised Georg Fischer distributor, BigWeld supplies the PROGEF Type 127 series in diameters from d16 to d63 mm for reliable industrial automation.
