RETZ工业/美国瑞茨，我们一直致力于流体控制领域的持续创新，始于2005……进口内螺纹PFA气动隔膜阀、高洁净氟塑料膜片阀的启闭件是一块用软质材料制成的隔膜，把阀体内腔与阀盖内腔及驱动部件隔开，整体材料采用PFA件，隔膜使用PTFE材质，对高纯高腐蚀性化学品有较好的耐受性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 PVDF material, and the diaphragm is PTFE material, which has good resistance to high-purity and high corrosive chemicals
