丹富斯氣動V型球閥-產(chǎn)品概述氣動V型球閥/氣動球閥原理
氣動V型球閥采用圓柱型彈簧預(yù)載的帶補償性可動金屬閥座結(jié)構(gòu)，密封性能可靠。球芯與閥座不會產(chǎn)生卡阻或脫離，使用壽命長。氣動V型球閥/氣動球閥原理
丹富斯氣動球閥球芯上的V形切口與金屬閥座之間具有剪切作用，特別適用于控制高粘度，含纖維、固體顆粒及漿料等介質(zhì)。結(jié)構(gòu)制造紙工業(yè)的紙漿顯得尤為*。
閥門的流通能力大、壓力損失小、且介質(zhì)不會沉積在閥體中腔，閥門不僅具有近似等有分比的流量特性、可調(diào)范圍大，zui大可調(diào)比為100：1，還具有精確調(diào)節(jié)與可靠定位的功能。

Dan fuss pneumatic V type ball valve - product overview
Pneumatic V type ball valve adopts the cylindrical spring preload with compensatory metal valve seat structure, reliable sealing performance. Ball core and valve seat won't produce jam or out, long service life.
Dan fuss pneumatic ball valve with the metal seated ball core of v-shaped incision with shearing action between, especially suitable for the control of high viscosity, fiber, such as solid particles and slurry medium. The pulp paper industry is particularly advantageous.
Valve flow capacity is big, small pressure loss, and the media will not deposit lumen in the valve body, valve not only has the approximate points than flow characteristic, such as wide tunable range, maximum adjustable ratio of 100:1, and also has the function of precise positioning adjustment and reliable.
