PROGEF PP-H Ball Valve Type 546 Pro DA Pneumatic

  Datasheet (PDF)

The Georg Fischer PROGEF Standard PP-H Type 546 Pro pneumatic ball valve delivers reliable automated flow isolation and control in demanding industrial chemical processes, water treatment systems, and process piping. Manufactured by Georg Fischer (GF Piping Systems), this valve assembly combines a robust beta polypropylene homopolymer valve body with a double-acting pneumatic actuator. Engineered for rapid and secure cycling, it features SDR11 butt fusion spigots rated for nominal operating pressures up to 10 bar at 20 degrees Celsius across sizes from 20 mm to 110 mm.

Technical specifications

The double-acting pneumatic actuator utilizes standard 5.6 bar instrument air for both opening and closing strokes, eliminating internal spring failure risks. It is fully equipped with standardized automation interfaces to integrate seamlessly into modern process control architecture.

• Actuation type: Double-acting (DA) PPA pneumatic actuator utilizing air supply for both opening and closing cycles at 5.6 bar control pressure.
• Nominal pressure rating: PN10 (10 bar at 20 degrees Celsius).
• Automation interface: Standardized NAMUR interface complying with VDI/VDE 3845 for direct attachment of solenoid pilot valves, positioners, and limit switch boxes.
• Position indication: Integrated high-visibility optical indicator providing immediate local visual confirmation of valve status.
• Stem safety feature: Engineered shear point in the valve stem prevents external media release during actuator torque overloads.

Materials and standards

Constructed entirely from high-grade industrial thermoplastics and performance fluoropolymers, this valve assembly guarantees extended service life and superior resistance to aggressive chemicals. Every assembly conforms to rigorous European and international pressure piping and leakage testing standards.

The valve body is manufactured from isotactic beta-PP-H (polypropylene homopolymeride), delivering exceptional thermal stability and chemical resilience. The ball mechanism seals against low-friction PTFE seats backed by resilient EPDM or FKM elastomeric backing rings. Shut-off integrity complies fully with EN 12266 and ISO 9393-2 leak rate A criteria, ensuring bubble-tight isolation. In addition, the actuator housing is moulded from flame-retardant, glass-fibre reinforced polypropylene (PP-GF), offering outstanding durability against ambient corrosive atmospheres.

Installation and jointing

The valve body incorporates extended SDR11 butt fusion spigots designed for homogeneous thermal welding into polypropylene pipe networks. These long spigots are fully compatible with conventional butt fusion equipment as well as advanced infrared (IR) welding systems.

Integrated stainless steel threaded inserts positioned in the valve base simplify mechanical pipe support and secure bracket anchoring. Maintaining the standardized z-dimension across metric sizes from d20 to d110 mm, the Type 546 Pro facilitates direct, drop-in replacement and retrofitting of legacy Type 546 valves without pipeline modification.
