8690型一体化安装于工艺阀门控制 burkert
类型 8690 - 适用于一体化安装于工艺阀门上的气动控制装置
类型描述
气动控制装置 8690 型是专为在 21XX 系列工艺阀门上实现一体化安装而设计的。机械或感应式限位开关检测阀门位置。一体化辅助阀可控制单倍或双倍作用的驱动器。控制装置和调节驱动器的设计可在无外部软管系统的情况下实现内部的控制空气传输。除电子位置反馈信息外,还会在气动控制系统上自行显示设备状态。由耐化学腐蚀的材料制成的壳体具有易清洁性,且其 IP 防护符合实际,可应用于食品工业、饮料工业和制药工业的卫生工艺技术中。利用控制按钮中的超压状态,壳体的 IP 防护可专为设备清洁提供支持。在与 Bürkert ELEMENT 系列驱动器的组合中,气动调节系统可实现弹簧腔室通风,由此可避免驱动腔室受到环境污染。

Type 8690 - Pneumatic control unit for decentralized automation of ELEMENT process valves
Type Description
The pneumatic control unit Type 8690 is designed for decentralized automation of ELEMENT Type 21xx pneumatic process valves. Mechanical or inductive limit switches register the position of the valve. The integrated pilot valve controls single or double-acting actuators. The design of the control unit and the actuator enables an internal control air channel without external tubings. Besides the electrical position feedback signal the status of the device is shown directly on the Control Unit itself. The housing is easy to clean and features proven IP protection and chemically resistant materials for use in hygienic processing, in food, beverage and pharmaceutical industries. Combined with Bürkert ELEMENT actuators the unique pilot valve system enables a compressed air recycling that avoids actuator chambers contamination from the environment.
