Cost effective mixproof valve

Alfa Laval Unique mixproof valves feature two independent plugs, which means that a single Unique mixproof valve can often replace two or more valves of other types.

Exceptional spillage-free operation

A state-of-the-art double-seat design provides long-lasting, spillage-free operation thus minimizing the risk of product contamination. The use of double lip seals provides added protection to ensure safe and hygienic operation.

Easy valve to maintain and clean

Unique mixproof valves feature a top-loaded design, making maintenance fast and easy. It also features no adjustable components, a maintenance-friendly actuator and built-in leakage detection on all seals. Unique mixproof valves meet most hygienic standards and can be supplied with the optional SpiralClean cleaning system.

独特的防混阀概念基于一系列基础组件,包括阀体、阀芯、执行器和清洁选项,以及支持广泛应用的附件。 使用这些组件,您可以构建独特的防混阀,以满足您的精确工艺要求。

为方便维护,阿法拉伐独特的防混阀还具有泄漏检测孔,可预先告知静态 O 形圈的磨损或损坏情况。 操作员无需拆卸阀门,就可以随时直观地检查阀门。



为了分离两种液体,阀门有两个独立的塞子密封。两个密封件之间的空间形成大气泄漏室。 在偶然产品泄漏的罕见情况下,产品流入泄漏室,并通过泄漏出口排出。

打开阀门时,泄漏腔关闭。 此时产品可从一条管路流至另一条管路,而没有溢出。 根据具体的工艺和阀门配置的需要,该阀门可以轻松地清洁,并防止水锤的影响。 (阀门操作期间没有产品溢出)。



SpiralClean 系统

阿法拉伐提供外部连接的CIP系统“ SpiralClean”。该系统可确保在要求苛刻的应用中实现卫生操作,在这些应用中,靠阀座提升和下推功能不足以清洁“独特防混服”。可以添加SpiralClean螺旋清洗系统以清洁上下阀座并冲洗阀的泄漏腔。与传统的外部连接的CIP设备相比,SpiralClean使用更少的清洁液,工具和时间,可以更彻底,更有效地进行清洁。
