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

  Datasheet (PDF)

The Georg Fischer 3-way ball valve type 543 Pro in PVC-C is a true union thermoplastic valve for mixing and diverting duties in industrial process piping from d16 to d63 mm. Rated PN10 and usable continuously up to 80 degrees Celsius, it is specified for chemical dosing, industrial water treatment and surface processing lines where aggressive acids, alkalis and oxidising media rule out metal valves.

Technical specifications

Flow is routed by a precision-machined ball supplied either as a horizontal L-port for 90 degrees diverting or as a T-port for multi-line mixing. The handle travels through a full 360 degrees and accepts a clip-on 90 degrees turn limiter for defined switching positions.

• Solvent cement socket sizes d16 to d63 mm, nominal pressure PN10 over the whole range
• Continuous operating temperature up to 80 degrees Celsius with aggressive process fluids
• L-port or T-port ball geometry, 360 degrees travel with clip-on 90 degrees limiter
• Ergonomic handle with locking lever for fail-safe manual operation
• Actuator top flange to DIN/ISO 5211, F03 and F04 patterns
• Integrated stainless steel 1.4404 (316L) female inserts in the valve base

Materials and standards

Body, ball and end connectors are produced in chlorinated polyvinyl chloride (PVC-C, Agate Grey RAL 7038), a heat-resistant compound with high resistance to concentrated acids, alkalis and oxidising media. Sealing is handled by low-friction PTFE ball seats backed by EPDM or FKM elastomer seals, selected according to the medium carried.

Socket dimensions comply with ISO 727 and ISO 15493, while face-to-face lengths follow EN 558 and ISO 5752 Series 10, so the valve replaces equivalent fittings without re-dimensioning the line. The actuator interface conforms to DIN/ISO 5211.

Installation and jointing

The valve is jointed to metric PVC-C pipe by solvent cement socket connection, with true union ends that allow the body to be removed for service without cutting the pipework.

The stainless steel inserts moulded into the base take bracket fixings, giving a vibration-proof anchorage on skids and dosing panels. The standardised top flange accepts Georg Fischer EA25 electric actuators or pneumatic drive units, so a manually operated valve can be automated later without changing the body or the pipe connections.
