A butterfly valve is a quarter-turn rotational shut-off device designed to control fluid flow within piping systems. Manufactured in compliance with ISO 5752 or API 609 standards, these valves typically feature discs made from stainless steel, cast iron, or ductile iron, paired with resilient seats like EPDM or PTFE to ensure tight sealing and minimal pressure drop.
Ensure the operating temperature and pressure do not exceed the seat material limits to prevent leakage. Regularly inspect disc alignment and actuator torque settings to avoid mechanical binding. Replace elastomeric seals periodically based on cycle frequency and chemical exposure to maintain system integrity.
