Georg Fischer PROGEF Standard Butterfly valve type 567 / Hand lever with ratchet settings 

The Georg Fischer PROGEF Standard Butterfly Valve Type 567 combines reliability, durability, and precision engineering to deliver peak performance for industrial pipeline systems. Constructed from fiberglass-reinforced polypropylene (PP-H/PP-R), this valve offers a lightweight alternative to traditional metallic valves without compromising strength or functionality. It’s designed for easy integration, with ISO 7005 PN 10 and ANSI/ASME B 16.5 compatibility, and provides secure hand lever operation with a standard 5° ratchet setting for precise control—optional fine adjustments available for enhanced precision. Engineered to withstand challenging conditions, this valve features high corrosion resistance with all media-contacting components made of resilient plastic. A double eccentric operating principle minimises wear and torque requirements, reducing actuating torque by up to 50% compared to centric valves for effortless operation. Dual internal shaft seals ensure double-sided tightness, delivering superior leak prevention both internally and externally. The modular design further enhances versatility, while the optional integrated electric position indicator improves operational monitoring. Perfect for demanding industrial applications, the Georg Fischer PROGEF Standard Butterfly Valve Type 567 prioritises efficiency and durability, ensuring long-lasting performance and minimal maintenance.
