BURKERT膜片阀175128由一个气动的活塞驱动装置、一个隔膜以及一个二通阀体构成。带有不锈钢套的高品质驱动装置，确保了在卫生或侵蚀性环境条件下的使用。利于流动的*阀体，能够实现较高的流量值和多样化的使用可能性。驱动装置设计允许将自动化单元简单地集成到所有结构分级中，从电气/光学位置反馈装置，经过气动的控制装置，直至集成式总线接口和防爆的设备类型。高度集成的系统由阀门和自动化单元构成，其特征在于设计的紧凑性和表面光滑性、集成式的控制空气管道、防护级 IP65/67/NEMA4X 以及高化学抗性。
BURKERT膜片阀175128特点：
有利于流动且*的外壳
通过隔膜将介质与驱动装置严格分离
自动化单元及 ELEMENT 的简单集成
带有连接套头、压合接头或焊接接头的不锈钢外壳
获得 FDA 认证
