3-Way Ball Valve PP-H Type 543 Pro T SDR11

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 543 Pro 3-way ball valve with horizontal T-port configuration is designed for dividing, mixing, and diverting aggressive media in industrial process piping. Fabricated from unpigmented beta polypropylene homopolymer (β-PP-H), this valve integrates metric long spigots for SDR11 butt fusion and infrared (IR) welding. Rated for a nominal operating pressure of 10 bar (PN10) at 20 degrees Celsius, it complies fully with ISO 9393-2 and EN 12266 leak rate A test standards, delivering reliable fluid isolation across chemical distribution, water treatment, and industrial installations.

Internal flow control is managed through a precision T-bore ball supported by low-friction PTFE ball seats backed by elastomeric compensation rings in EPDM or FKM. This resilient sealing arrangement ensures leak-tight closure, high chemical endurance, and uniform operating torque throughout extensive duty cycles. The body features integrated stainless steel threaded inserts on its base, allowing direct, strain-free anchoring to pipe support systems such as KLIP-IT or structural brackets without stressing the thermoplastic piping. Manual operation is handled by an ergonomic, lockable lever equipped with an enclosed 90 degrees turn limiter and visual position index, preventing accidental over-rotation.

Built on the modular architecture shared with the Type 546 Pro generation, this 3-way valve incorporates true double union ends with compatible union nuts, enabling quick radial removal and zero-stress maintenance in industrial skids. The interface accommodates direct retrofitting with pneumatic or electric actuators—featuring flame-retardant PP-GF housings—as well as optical LED position feedback sensors without disassembling the valve from the line. The robust β-PP-H material provides superior thermal stability, high impact resistance, and an operational service life of up to 25 years.
