BURKERT膜片阀2033系列用于控制高纯度、无菌、侵蚀性或磨损性介质。这种阀门具有很小的死角体积，能够实现*的容器灌注和排空过程。阀体由一个锭块构成，该锭块无焊缝，由优质不锈钢制造而成。底部排放阀的法兰具有两个斜角。这种结构简化了其在容器中的定位和焊接过程。高品质的隔膜将临界性介质与伺服驱动装置密封分离。通过气动先导式阀（单个先导式阀、阀岛或控制头），可以控制气动的伺服驱动装置。控制功能 A，通过弹簧力在静止位置关闭。
BURKERT膜片阀2033系列特点：
*的外壳，没有焊缝
通过隔膜将介质与驱动装置严格分离
坚固的通用驱动装置，具有模块化配件系列
带有焊接接头的不锈钢外壳
质量认证 FDA / 3A
