Common faults of butterfly valves

The rubber elastomer in butterfly valves will tear, wear, age, perforate and even fall off during continuous use. The traditional hot vulcanization process is difficult to meet the needs of on-site repair. Special equipment is required for repair, which consumes a large amount of heat and electricity, which is time-consuming and labor-intensive. Today, polymer composite materials are gradually being used to replace traditional methods, among which the Fu Shilan technology system is the most widely used. The superior adhesion and excellent wear and tear resistance of its products ensure that the service life of new parts can be reached or even exceeded after repair, greatly shortening downtime.
