The shelf life of flange butterfly valve is usually 12 months, starting from the date of the user's acceptance of the product, based on the date of the acceptance delivery list, or 7 days after the date of the certificate of conformity and the contract signing. However, the actual service life will be affected by many factors, including medium characteristics, working environment, operation frequency, maintenance, and valve quality and brand.
Main factors affecting the service life of flange butterfly valve
Media characteristics: If the medium is highly corrosive, abrasive, or has extreme conditions such as high temperature and high pressure, it will accelerate the wear and corrosion of valve parts and shorten the service life.
Working environment: Harsh environmental conditions such as humidity, dust, corrosive gases, etc. may cause valve parts to rust, corrode or damage.
Operation frequency: Frequent switching operations will increase the wear of valve parts, thereby affecting the service life.
Maintenance: Regular maintenance, maintenance and repair can detect and solve potential problems in time and extend the service life of the valve. Lack of proper maintenance may cause valve performance to deteriorate and damage in advance.
Quality and Brand: Valves of different brands and qualities have differences in manufacturing processes and materials that will affect their service life. High-quality products are usually more durable.
