該系列調(diào)節(jié)閥的 V 形切口球面閥板在增大調(diào)節(jié)比的同時(shí)，在截流時(shí)對(duì)密封環(huán)還具有剪切作用。因此， 適用于要求大調(diào)節(jié)比的控制系統(tǒng)，以及對(duì)含纖維質(zhì)流 體、料漿類(lèi)流體的控制，是一種用途廣泛的調(diào)節(jié)閥。

This series is concentric segmental ball valve for modulating application. V-notch cut at disc makes rangeability larger and creates shearing effect by disc and seal ring. Therefore, suitable to large rangeability service and/or control of fluids with fiber and/or slurry.
