3-Way Ball Valve 543 Pro PVC-C d16-d63 PN10

  Datasheet (PDF)

The Georg Fischer 3-way ball valve type 543 Pro PVC-C is an engineered thermoplastic valve designed for demanding mixing and diverting operations within industrial process piping systems. Built from post-chlorinated polyvinyl chloride (PVC-C), this valve provides exceptional chemical resistance against concentrated acids, alkalis, and oxidizing media, while maintaining mechanical rigidity at elevated operational temperatures up to 80 degrees Celsius. Rated for nominal operating pressures up to 10 bar (PN10), the valve is tailored for aggressive media distribution, chemical dosing units, industrial water treatment plants, and surface finishing operations where metallic valves suffer from corrosive degradation.

At the core of the 543 Pro platform is a precision-machined ball with horizontal L-port or T-port geometries, supported by low-friction PTFE ball seats and chemical-grade elastomer backing seals in either EPDM or FKM. The integrated true union architecture incorporates metric solvent cement sockets from d16 mm to d63 mm, enabling straightforward installation and stress-free radial demounting without disassembling adjacent pipeline sections. The valve body features integrated stainless steel threaded inserts (SUS316L / 1.4404) at the base, ensuring rigid and standardized mounting onto industrial bracket assemblies or automation support frameworks.

Designed for modular versatility, the valve features a full 360 degrees operational angle accompanied by a clip-on 90 degrees turn limiter for precise manual diversion control. The multifunctional handle integrates an ergonomic locking lever, while the drive shaft and upper housing adhere to DIN/ISO 5211 mounting standards. This standardized mechanical interface facilitates seamless field retrofitting with Georg Fischer electric actuators (such as the EA25 series) or pneumatic actuation units, position feedback switches, and smart digital positioners without replacing the valve core. Strict backward compatibility with earlier type 543 face-to-face dimensions and type 546 union nuts guarantees hassle-free modernization of existing industrial piping networks.
