Service life of bidirectional sealed butterfly valves

Service life of bidirectional sealed butterfly valves
Bidirectional sealing butterfly valve is a common industrial valve widely used for the control and regulation of liquid, gas, and particulate materials. Its service life refers to the valve's ability to maintain good sealing performance and reliable operating time under normal working conditions.
Firstly, the service life of a bidirectional sealed butterfly valve is related to its material. At present, the common materials for two-way sealed butterfly valves in the market mainly include cast iron, ductile iron, steel, stainless steel, etc. These materials have different corrosion resistance and wear resistance, therefore their service life also varies. Generally speaking, stainless steel two-way sealed butterfly valves have a longer service life of over 20 years, while cast iron two-way sealed butterfly valves have a shorter service life of about 10 years.
Secondly, the service life of bidirectional sealed butterfly valves is related to the stability of their sealing performance. Sealing performance is one of the important indicators of bidirectional sealing butterfly valves, which directly affects the service life of the valve. During the use of bidirectional hard sealing butterfly valves, the sealing ring material of the bidirectional sealing butterfly valve will gradually age, wear and deform, leading to a decrease in sealing performance. In order to extend its service life, the sealing ring can be regularly maintained and replaced to maintain its good sealing performance. In addition, reasonable selection and use of butterfly valve operation methods to avoid excessive pressure difference and frequent opening and closing operations can also reduce the impact on sealing performance and extend the service life.

In addition, the service life of bidirectional sealed butterfly valves is also related to their working environment. Bidirectional sealed butterfly valves are usually used in industrial pipelines, and their working environment may have adverse factors such as corrosive media, high temperature, and high pressure. These factors will have an impact on the material and sealing performance of the valve, thereby affecting its service life. Therefore, when selecting and installing bidirectional sealed butterfly valves, it is necessary to select suitable materials and models based on specific working environment requirements to ensure that the valve can operate normally in harsh environments and achieve the expected service life.
In addition, the service life of bidirectional sealed butterfly valves is also related to their usage conditions and maintenance. The usage conditions include the pressure, temperature, and medium of the valve. Excessive pressure or temperature may cause deformation, aging, and damage to the valve material, thereby reducing its service life. Maintenance work includes regular inspection, lubrication, cleaning, and replacement of worn parts. Regular inspections can promptly identify and address existing problems, extending the service life of the valve. Lubrication and cleaning can maintain the flexibility and normal operation of the valve, while replacing worn parts can restore the sealing performance and effective sealing time of the valve.
In summary, the service life of bidirectional sealed butterfly valves is influenced by multiple factors, including material, sealing performance, working environment, usage conditions, and maintenance. In order to extend the service life of bidirectional sealed butterfly valves, it is necessary to pay attention to the above factors during selection, installation, and use, and carry out appropriate maintenance and upkeep. Only by ensuring the suitability of the valve material, stability of sealing performance, and adaptability to the working environment can the bidirectional sealing butterfly valve achieve a longer service life.
