GF Piping Systems presents the new 567/568 type series of butterfly valves with a comprehensive range of products and a multitude of interesting combination possibilities. We can offer you, for example, manual valves with hand lever or reduction gear. The Type 567 and 568 Butterfly Valves is available in large diameter sizes up to eight or 24 inches, depending on model. The valves feature a disc and liner made of PVDF (polyvinylidene fluoride) and PTFE (polytetrafluorethylene) seals to provide superior chemical resistance and performance capabilities across a wide temperature range.
Our system's modular design principle allows you to exchange individual system components - fast, easily and at very little expense. You also have a choice of materials: PVC-U, PVC-C, ABS, or b-PP-H and PVDF.
Our standard sealing materials are EPDM and FPM, but other materials are available on request.
All the customary installation pipe standards are supplied:
Thermoplastic valves - pressure test methods and requirements
Face-to-face length of butterfly valves corresponds to EN558
