PVC-C Type 546 Pro DA Pneumatic Ball Valve 10 Bar

  Datasheet (PDF)

The Georg Fischer PVC-C Type 546 Pro DA Ball Valve delivers dependable automated flow control in demanding industrial process piping systems. Actuated by a high-efficiency double-acting (DA) pneumatic actuator enclosed in a robust, glass-fibre reinforced polypropylene (PP-GF) housing, this valve operates seamlessly at a standard control pressure of 5.6 bar. Designed for aggressive chemical media and high-temperature service where standard plastics fail, it provides reliable on-off isolation across a broad spectrum of industrial applications.

Constructed entirely from premium post-chlorinated polyvinyl chloride (PVC-C in Agate Grey RAL 7038), the valve body exhibits outstanding chemical resistance against concentrated acids, alkalis, and corrosive salts at operating temperatures up to 80 degrees Celsius. The fluid path incorporates low-friction PTFE ball seats paired with high-grade EPDM or FKM elastomeric seals, ensuring smooth quarter-turn actuation, tight shut-off, and reduced operational torque even after long idle periods.

The assembly features an integrated NAMUR interface compliant with VDI/VDE 3845, allowing direct, standardized mounting of pilot solenoid valves, limit switch feedback boxes, and digital positioners. An integrated visual indicator provides immediate optical feedback of the valve position. For secure pipe anchoring and bracket attachment, the valve base incorporates integrated stainless steel mounting inserts, preventing stress transmission to the thermoplastic pipework during high-cycle pneumatic operations.

Connection to the process line is executed via metric solvent cement sockets designed for solvent cementing according to ISO standards. Standardized z-dimensions and union nuts guarantee full modularity and backward compatibility with earlier first-generation Type 546 installations. BigWeld supplies this automated valve as an authorised Georg Fischer distributor, supporting industrial installations with precision engineering components that meet the highest standards of process safety and operational durability.
