ABS Ball Valve Type 546 Pro PN10 d75-d110 ISO

  Datasheet (PDF)

The Georg Fischer Type 546 Pro ABS ball valve provides reliable isolation and precise flow regulation in cooling loops, chilled water circuits, marine installations, and industrial water treatment systems. Manufactured to ISO standards, this radial double-union valve is rated for PN10 nominal pressure (10 bar at 20 degrees Celsius) across dimensions from d75 (DN65) up to d110 (DN100). It combines high chemical compatibility for neutral and cooling fluids with the robust impact strength typical of industrial ABS thermoplastics.

Constructed with a heavy-duty ABS body, low-friction PTFE ball seats, and high-elasticity EPDM seals, the valve delivers bubble-tight shut-off and low actuation torque. The valve architecture includes integrated stainless steel threaded inserts in the base, enabling solid mechanical mounting without applying piping stresses to the valve body. Designed for seamless plant servicing, the 546 Pro series preserves identical z-dimensions, union nuts, and valve ends with first-generation Type 546 units, allowing immediate retrofitting into existing pipeline infrastructure.

Supplied as standard with an ergonomic lockable lever, the valve prevents accidental operation in critical utility networks. Its modular upper interface supports straightforward conversion to automated operation via electric or pneumatic actuators, as well as integration with position feedback switches and spring-return safety handles.
