Type Description
The bellow control valve is a pneumatically operated process valve with a single-acting diaphragm actuator. A PTFE bellow ensures the separation between medium and actuator. The materials used and the design of the media space allow the use under hygienic or aggressive conditions. It has a good cleanability. The combination with a controller (Type 869x) and the control cone integrated into the bellow enable the valve to handle demanding control tasks. The space-saving actuator with low internal volume not only results in a very compact size but also in remarkably low response times. The valve is characterized by a good control performance due to the low-friction design and has a linear characteristic. A certain variety of body and block system solutions are deliverable.
1）For neutral and aggressive media
2）Media separation by PTFE bellow
3）Hygienic design
类型描述
波纹管式调节阀是一款气动操作的过程阀门，配有单动式膜片驱动器。PTFE 波纹管可保障介质和驱动器安全分离。所使用的材料和介质室的设计允许其在医疗卫生环境或腐蚀性环境中使用。可轻松方便地清洁调节阀。通过与调节器（型号 869x）组合和集成于波纹管中的调节轮廓，可完成高要求的调节任务。驱动器内部容量小，非常节约空间，这不仅使得其结构极为紧凑，同时也可大幅度缩短反应时间。因无摩擦的结构，阀门具有良好的调节性能及直线型特征曲线。另有多种壳体和区块解决方案可供选择。
（1）适用于中性和腐蚀性介质
（2）通过 PTFE 波纹管分离介质
（3）医疗卫生设计
