Georg Fischer Butterfly valve type 567 PVC-C - Hand lever with ratchet settings 

The Georg Fischer Butterfly Valve Type 567 PVC-C combines precision engineering with innovative design to deliver dependable performance for a wide range of pipeline applications. Constructed from durable, corrosion-resistant PVC-U, this valve is ideal for environments where metallic options might succumb to harsh chemicals or corrosive substances. Its lightweight fiberglass-reinforced plastic housing ensures easier handling and installation without compromising strength or reliability. Equipped with a lockable, ergonomic hand lever featuring 5° ratchet settings, the valve offers precise control and secure operation, making it a practical choice for specialists who value performance and safety. The advanced double eccentric operating principle minimises wear, extending the valve's lifespan for long-term savings. With optimised modular components, including a double internal shaft seal on both sides, this valve is designed to maintain performance and reduce maintenance needs. Compliant with international standards such as EN558, ISO 5752, and ANSI/ASME B 16.5 CLASS 150, the Butterfly Valve Type 567 provides seamless compatibility with various connection dimensions, making it an adaptable solution for diverse projects. 

Summary:
