Linear Ball Valve 546 Pro L ABS PN16 DN10-DN50

  Datasheet (PDF)

The Georg Fischer Linear Ball Valve 546 Pro L ABS is an industrial regulating valve engineered for precise linear flow control in thermoplastic piping systems. Intended for process engineers and industrial installers, it pairs a profiled control ball with the proven 546 Pro platform and covers metric solvent cement socket sizes from d16 mm to d63 mm (DN10 to DN50) at a nominal pressure rating of PN16 at 20 degrees Celsius.

Technical specifications

The linear control ball produces a proportional, predictable flow characteristic over the 90 degrees operating stroke and avoids cavitation instability across the whole regulating curve. Pure PTFE ball seats backed by high-grade EPDM seals keep operating torque low and chemical resistance stable over the service life.

• Body material: high-impact ABS, metric range in RAL 7001 gravel grey
• Seat and sealing: chemically inert pure PTFE seats with EPDM elastomer seals
• Pressure rating: PN16 (16 bar at 20 degrees Celsius)
• Connections: true union metric solvent cement sockets, d16 mm to d63 mm (DN10 to DN50)
• Operation: lockable ergonomic hand lever with fine index scale, 90 degrees stroke
• Mounting: integrated stainless steel threaded inserts in the valve base

Applications

ABS piping components are selected where low-temperature toughness and ductile behaviour are required, which makes this regulating valve suited to cooling circuits, chilled water distribution and water treatment.

Typical duties include secondary refrigeration loops and chilled water branches that have to be throttled to a repeatable setpoint, as well as process water and marine installations covered by the Georg Fischer ABS range. The indexed lever allows the same flow setting to be restored after maintenance without re-balancing the circuit.

Installation and jointing

The valve is jointed by solvent cementing into ABS sockets using Tangit ABS cement, with the surfaces prepared beforehand using the matching cleaner and primer. The true union body lets the valve be removed for service without cutting the line.

The modular housing accepts Georg Fischer pneumatic or electric actuators and digital positioners without altering pipe alignment, so manual units can be automated later. The stainless steel inserts in the base allow rigid fixing to brackets and supports, keeping structural pipe loads away from the valve body.
