Description
The GF ABS Metric 3-Way Ball Valve – L-Port is a high-quality manual valve designed for diverting and switching flow paths within metric ABS pipework systems. Manufactured by Georg Fischer, this valve forms part of the proven Type 543 Pro range and is ideal for applications requiring reliable flow control, long service life and future automation capability.
The L-port ball design allows flow to be directed from one inlet to one of two outlets, making it suitable for diverting duties and line selection. A lockable lever is supplied as standard, allowing the valve position to be secured every 90° for improved operational safety and control.
Constructed from ABS with PTFE ball seats and seals, the valve offers excellent chemical resistance and smooth flow characteristics. Integrated stainless steel mounting inserts and ISO-compatible dimensions allow straightforward retrofitting of electric or pneumatic actuators if automated control is required at a later stage.
