氣動(dòng)轉(zhuǎn)閥的作用是實(shí)現(xiàn)定量送料，以防止過多的物料堵塞粉碎整粒機(jī)，造成對(duì)設(shè)備的損害。通過氣動(dòng)定時(shí)器的控制可以很好的控制對(duì)粉碎整粒機(jī)的給料量。
    氣動(dòng)轉(zhuǎn)閥的閥芯安裝于上罐體出口處。在轉(zhuǎn)閥閥體圓柱形通道內(nèi)，其*的星形葉片繞著軸線按正、反兩方向作180°旋轉(zhuǎn)，既可達(dá)到均勻放料的目的，又可有效防止泄料現(xiàn)象的發(fā)生。

The Application of this product can realize the quantitative feeding, and avoid that the overmuch material block up the Grinding and granulate machine and than damage the machine. By the controlling of PZVT-120-SEC, it can well control the feeding amount to the Grinding and granulate machine.   

The Valve Spool of this product is installed on the exit of Hopper. In the cylindrical channel of valve body, the peculiar radial blade revolve （180 degrees） around the axis in either of two opposite directions. It's for regular baiting and effectively preventing the material leakage.   

★ 結(jié)構(gòu)簡(jiǎn)單，便于清潔 ；

Simple structure, Convenient cleaning
★  光潔度高，優(yōu)于傳統(tǒng)的“星形閥”；

Good surface finishing, better than traditional "Star Type Valve"
★ 只有在關(guān)閉位置，轉(zhuǎn)閥才停止轉(zhuǎn)動(dòng)，可防止物料泄露 ；

    Just on the Closed position, the Rotary Valve will be stopped. It can avoid the material leakage
★  由于接觸面小，粉體與密封圈摩擦力小，使用更省力無需潤(rùn)滑劑；

   Because of the small interface, the frictional force between powder with sealing is very small, and than, it will be used more save effort and no need lubricant 

★  不需要潤(rùn)滑劑 ；

No need lubricant

★  符合CIP和GMP要求；

 Meet the CIP & GMP demands

★ 可連續(xù)供料 ；

Keeping the feeding

★ 當(dāng)閥門關(guān)閉時(shí)可承受一定的正壓或負(fù)壓。
