Description
The Georg Fischer 3-way T-port ball valve (Type 543) is a high-quality flow control valve designed for applications requiring diversion, mixing or multi-directional control within PVCu pipework systems. The T-port ball configuration allows multiple flow paths depending on valve position, making it suitable for more complex arrangements than standard 2-way isolation valves.
Manufactured from PVCu, the valve offers excellent corrosion resistance and durability, with EPDM body seals and PTFE ball seals providing reliable shut-off and smooth operation. Socket union ends are designed for solvent cement welding, allowing the valve to be securely installed while remaining fully demountable for maintenance. The valve end and union nut dimensions are compatible with Georg Fischer Type 546 valves, simplifying replacement or system upgrades.
The valve features a lockable lever as standard, along with unrestricted 360° operation and an enclosed 90° turn limiter that can be positioned as required. Integrated stainless steel mounting inserts make the valve suitable for automation, with options for electric or pneumatic actuation and position feedback sensors.
