This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
The resilient seat butterfly valve, also known as a centerline butterfly valve, is a component used for controlling flow and isolating sections in piping systems. The structural feature of the centerline butterfly valve is that the stem axis, the center of the butterfly disc, and the center of the body are all aligned in the same position. This design is simple and easy to manufacture. A common example of this type is the rubber-lined butterfly valve.
