3-Way Ball Valve 543 Pro PVC-C Horizontal T-Port 10 Bar

  Datasheet (PDF)

The Georg Fischer Type 543 Pro PVC-C 3-way ball valve is engineered for precise mixing and diverting in industrial piping systems. Featuring a horizontal T-port configuration, it facilitates versatile flow direction control across multi-branch networks. The valve body is manufactured from post-chlorinated polyvinyl chloride (PVC-C) in agate grey RAL 7038, delivering high mechanical stability and resistance to aggressive acids, bases, and salts. Operating reliably at temperatures up to 80 degrees Celsius under pressure, it is built for demanding chemical duties.

Engineered for process safety, the Type 543 Pro incorporates low-friction PTFE ball seats with durable EPDM or FKM backing seals. A lockable ergonomic lever is supplied as standard to prevent accidental operation. The valve mechanism permits continuous 360 degrees rotation while including a clip-on turn limiter that restricts actuation to 90 degrees intervals. Integrated stainless steel 1.4404 threaded inserts at the base allow secure bracket mounting, isolating the plastic piping from external mechanical loads.

The modular design ensures rapid integration into piping networks via metric solvent cement sockets. It retains backward compatibility with Type 546 union nuts and Type 543 first-generation Z-dimensions. Standardized interfaces facilitate straightforward mounting of electric or pneumatic actuators according to EN ISO 5211. As an authorised Georg Fischer distributor, BigWeld supplies this valve for chemical processing, water treatment, electroplating, and semiconductor manufacturing.
