Description
The Georg Fischer 3-way L-port ball valve is engineered for controlled changeover duties where flow must be directed between two outlets while isolating the third port. Unlike T-port designs that allow multiple simultaneous flow paths, the L-port configuration provides a clear, defined flow direction, making it ideal for switching and selection applications within PVCu pipework systems.
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.
