品牌：RETZ瑞茨/我們一直致力于流體控制領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)口插入式PFA氣動(dòng)隔膜閥、高潔凈氟塑料膜片閥的啟閉件是一塊用軟質(zhì)材料制成的隔膜，把閥體內(nèi)腔與閥蓋內(nèi)腔及驅(qū)動(dòng)部件隔開，整體材料采用PFA件，驅(qū)動(dòng)器使用PPS材質(zhì)，隔膜使用PTFE材質(zhì)，對(duì)高純高腐蝕性化學(xué)品有較好的耐受性retz The opening and closing parts of imported internal thread PFA pneumatic diaphragm valves and high cleanliness fluoroplastic diaphragm valves are made of soft materials, which separate the valve body cavity from the valve cover cavity and driving components. The overall material is PFA parts, the driver is made of PPS material, and the diaphragm is made of PTFE material, which has good resistance to high-purity and high corrosive chemicals
