Application: used to extract the high-temperature/pressure (or vacuum) melt flow or polymer from pipeline and cut it directly. When the valve is shut off,the feeding mouth of plunger matches up with the internal wall of pipeline and provides no disturbance to the meld flow inside the pipeline. 適應(yīng)范圍：用于高溫高壓（或全真空）熔體流或聚合物從管線中直接提取出來(lái)及切斷，當(dāng)閥門(mén)關(guān)閉時(shí)，其柱塞配料口正好與管線內(nèi)表面相匹配，這樣不會(huì)干擾線里熔體的流動(dòng)。
