PROGEF PP-H Pneumatic Ball Valve 546 Pro FC SDR11

  Datasheet (PDF)

The Georg Fischer PROGEF Standard PP-H Type 546 Pro FC pneumatic ball valve provides fail-safe automated isolation and throttling for chemical distribution, industrial water treatment and effluent processing lines. Supplied by BigWeld, an authorised Georg Fischer distributor, it combines a beta polypropylene homopolymer (beta PP-H) body with a spring-return pneumatic actuator configured for fail-safe-to-close (FC) duty: should the control air supply fail, the heavy-duty internal springs drive the ball to the fully closed position, protecting downstream equipment and preventing uncontrolled chemical release.

The valve body is built with metric SDR11 butt fusion spigots in sizes d20 to d63, compatible with conventional butt welding and with infrared (IR-Plus) fusion, so it integrates directly into PN10 PROGEF Standard networks at a nominal pressure of 10 bar. The actuator housing is moulded in glass-fibre reinforced polypropylene (PP-GF), which resists the corrosive industrial atmospheres that degrade metallic drives. Actuation follows the standard NAMUR interface (VDI/VDE 3845) at a nominal control pressure of 5.6 bar, completing a 90 degrees cycle in 1 to 2 seconds, and the unit carries an integrated manual override for maintenance work plus an optical position indicator for immediate visual confirmation.

Internally, low-torque PTFE ball seats give bubble-tight shutoff to ISO 9393-2 and EN 12266 leak rate A, backed by EPDM or FKM elastomeric seals selectable per order. Stainless steel threaded inserts in the valve base allow vibration-resistant mounting onto supports or structural brackets without stressing the thermoplastic pipe. Face-to-face dimensions remain fully compatible with earlier Georg Fischer 546 and 230–235 series installations, so the unit can be fitted as a drop-in upgrade without modifying the line.
