PROGEF PP-H Ball Valve Type 546 Pro Butt Fusion SDR 17.6

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 546 Pro ball valve with SDR 17.6 butt fusion spigots provides reliable flow isolation for demanding industrial fluid networks, chemical processing systems, and water treatment plants. Manufactured from premium beta-PP-H (polypropylene homopolymer), this valve covers dimensions from d40 mm to d110 mm and operates reliably at a nominal pressure rating of 10 bar. Designed for process engineers and industrial piping specialists, it integrates true double union construction for dependable service and streamlined field maintenance.

Technical specifications

The Type 546 Pro incorporates a reverse-seated safety stem and dynamic sealing architecture to maintain steady torque and leak-tight operation under harsh industrial conditions. Its modular body platform ensures full backwards compatibility with legacy installations and accommodates pneumatic or electric actuators via standardized mounting interfaces.

Integrated stainless steel threaded bushings in the base allow direct, vibration-resistant anchoring to brackets without inducing mechanical stresses into the pipe run. The ergonomic hand lever features an integrated locking mechanism to prevent accidental repositioning during critical plant processes.

• Nominal pressure: Rated for working pressures up to 10 bar with leak rate A compliance.
• Dimensional range: Butt fusion spigot connection sizes from d40 mm to d110 mm.
• Stem design: Blow-out proof safety stem featuring a predetermined shear break point above primary seals.
• Sealing interface: Low-friction PTFE ball seats backed by resilient elastomeric backing rings.
• Actuation interface: Standardized mounting configuration for direct adaptation of electric or pneumatic actuators.

Materials and standards

Every wetted component is fabricated from high-grade beta-PP-H homopolymer combined with chemically resistant fluoropolymer and elastomeric seals. This material synergy delivers long-term durability against corrosive media, aggressive chemicals, and industrial effluents.

The valve body complies with pressure-bearing piping requirements under ISO 9393-2 and tight shut-off testing in accordance with EN 12266 leak rate A. Depending on operational fluid compatibility requirements, the unit is configured with factory-grade EPDM or FKM elastomeric seals supporting high-purity PTFE ball seats.

Installation and jointing

The extended spigot ends are specifically sized for SDR 17.6 piping systems, enabling homogeneous jointing via conventional butt fusion or contactless infrared (IR) fusion. True double union ends with buttress threads allow quick radial installation and dismounting without spreading adjoining pipe sections.

During installation, installers can easily disconnect the central valve body for inspection, seat replacement, or seal maintenance while the butt-welded spigots remain solidly joined in the pipeline. Direct mounting on KLIP-IT pipe supports or steel brackets relieves piping alignment stress and protects structural integrity.
