Butterfly Valve type 567/578 Type 567 Wafer-style installation Type 578 Lug-style installation Type 567/578 with reduction gear Type 567/578 with pneumatic actuator Product description Butterfly valves of types 567 and 578 are corrosion -resistant and reliable control and shut-off valves that can be used in most applications in industrial water treatment, the chemical process industry, chemical trade, galvanization and in power plants. The valves are intended for wafer-style and lug-style applications. They are compact, varied and reliable. The valve is modular in design, allowing individual system parts to be exchanged at any time. Benefits/features • Lower weight than metallic butterfly valves due to use of fiberglass-reinforced plastic as housing material • High corrosion resistance: all components that come into contact with media are made of plastic • Lockable ergonomic lever with standard 5° ratchet setting (fine adjustment as option) • Low wear due to double eccentric operating principle: up to 50 % lower actuating torque than with centric valves • Tightness in the passage and to the outside: double, double-sided, internal axis seal • Optimized modular components: double internal shaft seal on both sides • Standard interface conforms to ISO 5211 • Integrated electric position indicator (optional) • Type 578: Use as lugged valve with threaded inserts integrated into the housing GF Piping Systems – Industrial Piping Systems (04/2024)

Technical basics Function Butterfly valves of types 567 and 578 have a double-eccentric mode of action and are of modular construction. Double eccentric operating principle The disc does not touch the seal in the open position. The disc can be quickly unscrewed from the gasket, ensuring low wear and tear. Pressure surges in the direction of flow can be absorbed more readily. Use as a process and control valve The butterfly valves can be equipped with corresponding pneumatic or electric actuators and can be used with other extensive accessories as process and regulating valves. The integrated...

Maintenance notes In normal operation, butterfly valves do not require maintenance. It is still recommended to perform maintenance on butterfly valves after 5,000 actuation cycles at most. The following steps must be taken when doing so: • Regularly check that no medium escapes to the outside. If medium exits from the flange connections, tighten them. • We recommend operating the butterfly valves that are kept permanently in the same position 1-2x per year to check their functionality. • Depending on the operating conditions, the collars should be lubricated periodically with (silicon-based)...
