PP-H ball valve Type 546 Pro PPA DA

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 546 Pro pneumatic ball valve is an engineered quarter-turn flow control assembly designed for automated chemical processing, water treatment, and industrial distribution lines. Equipped with a double-acting PPA pneumatic actuator in a corrosion-resistant glass-fibre reinforced polypropylene housing, this PN10 rated valve delivers dependable isolation using instrument air for both opening and closing cycles without mechanical return springs.

Technical specifications

The Type 546 Pro PPA DA assembly pairs a balanced ball valve design with a high-efficiency double-acting pneumatic actuator. The system provides smooth quarter-turn rotation, rapid cycle times, and integrated visual status monitoring for demanding industrial automation setups.

• Nominal operating pressure: PN10 (10 bar rating across available sizes d20 to d63 mm).
• Pneumatic actuation: Double-acting (DA) PPA actuator driven by instrument air in both directions.
• Valve seating: Pure PTFE ball seals with elastomeric backing cushions in EPDM or FKM.
• Piping connection: Integrated fixed flanges conforming to standard ISO bolt circles.
• Interface mounting: VDI/VDE 3845 NAMUR pattern for direct pilot valve and sensor box mounting.
• Testing standards: Pressure and shell testing compliant with EN 12266 and ISO 9393-2 leak rate A.

Materials and standards

Engineered exclusively from high-grade thermoplastics, this valve assembly prevents both internal chemical erosion and external atmospheric corrosion. The housing and valve components withstand aggressive process fluids and humid industrial environments over an extended operating life.

The valve body is injection-moulded from beta-PP-H (isotactic polypropylene homopolymer), engineered for a 25-year service life in water distribution at 20 degrees Celsius. Actuator housings are moulded from flame-retardant glass-fibre reinforced polypropylene (PP-GF), while integrated stainless steel threaded inserts facilitate secure base mounting without stressing the thermoplastic pipework.

Applications

This automated PP-H ball valve configuration is specifically tailored for aggressive chemical handling and pure water automation loops. Its all-plastic external build makes it ideal for coastal plants, chemical dosing skids, and wet process environments where metallic actuators suffer from premature oxidation.

Standard installations include industrial effluent treatment, chemical processing lines, deionised water networks, electroplating processes, and automated distribution manifolds where double-acting air operation ensures precise holding in either the open or closed position.
