Lifespan of Butterfly Valves

The standard design lifespan of butterfly valves is typically over 10 years. Key performance indicators include: number of opening and closing operations (≥10,000 times), liquid seal (no leakage), and gas seal (leakage < national standard limit). Their lifespan is directly affected by material selection (e.g., stainless steel/corrosion-resistant alloy), regular maintenance (cleaning/inspection), and protective measures (installation of filters, anti-corrosion coatings). In harsh operating conditions such as those in the petroleum and chemical industries, these parameters are crucial for ensuring the stability of fluid control systems, for example, reducing the risk of downtime due to media leakage.
