Alfa Laval Unique PMO Plus® Mixproof Valve
The Alfa Laval Unique PMO Plus® mixproof valve offers all the performance of a Unique Mixproof valve and, in addition, meets the requirements of 3-A/PMO standards. The mixproof valve design allows clean-in-place (CIP) fluid to flow to clean one chamber while product is running in the other chamber, without the risk of cross-contamination. Eliminating clean-in-place (CIP) downtime and allowing automated product transfer are just two of the advantages that mixproofs provide. Unique PMO Plus Mixproof Valves combine Alfa's superior cleanability and reliability with the required features for meeting the PMO standard making it a powerful solution for dairy applications.
Unique PMO Plus valves are authorized to carry the 3-A symbol.
Alfa Laval is a leading global supplier of products and solutions within the key technology areas of heat transfer, separation, and fluid handling.
巴氏杀菌牛奶条例（PMO）
巴氏杀牛奶条例（PMO）第15P（b）段概述了使用混合阀在涉及牛奶产品和清洁溶液的应用中，以确保乳制品通过同一阀门同时流动的卫生产品的卫生和安全分离。
The PMO requires that:
- 阀座必须是可检测的位置
- 在所有混合阀中发现的泄漏室必须具有与阀体端口连接相同的横截面积
- The actuator must be fail-safe by spring-to-close
In 2007, the Food and Drug Administration (FDA) changed the PMO to allow clean-in-place (CIP) solution to clean one valve seat while product is flowing in the opposite housing. This change virtually eliminates CIP downtime, so processors can run continuous dairy operations and increase production.
2008年，FDA发布备忘录M-B-356，确认Alfa Laval独特的PMO Plus混合阀门是巴斯特尿乳条件第15P（B）兼容。
The following benefits make the Unique PMO Plus stand out from the competition:
- 经过验证的设计：Same fundamental technology used in the industry for more than a decade
- Retrofittable:Replacement of a few components enables conversion of installed Unique PMO valves to Unique PMO Plus
- Only three elastomers in the isolation chamber:Minimizes risk of product contamination
- 测试和符合145 psi的FDA：最高的操作压力可用于最广泛的过程应用
- 设计了d with a mix of radial and axial seals:A proven, leading design to protect product
- Standard, single unit actuator:Simple operation with fewer moving parts
- 与独特的PMO阀门相同的湿润和执行器服务套件：No need to learn or stock new parts
- 维护友好：No adjustments are required when reassembling the valve after service
Concept
这种独特的PMO加混合阀基于来自Alfa Laval的独特PMO混合阀的良好经过熟练的良好且非常灵活的设计。它符合3-A / PMO（巴氏杀牛奶条例第15P（B）段）标准的要求，说明所有运动都必须可检测到，以及通风管必须具有比连接管的相同或更大的面积。此外，独特的PMO Plus符合座椅升降顺应性M-B 356的FDA需求。这使得CIP流量在另一个室内运行的产品运行时清洁一个腔室，从而消除了CIP停机时间。最后，通过弹簧关闭，执行器是故障安全的。
工作准则
Unique PMO Plus is remote-controlled by means of compressed air. The valve is a normally closed (NC) valve. The valve has two independent plug seals, forming a leakage chamber between them which is at atmospheric pressure or less during every working condition. In the rare case of fluid passing a valve seat, the fluid will enter the leakage chamber and be discharged through the leakage outlet. When the valve is open, the leakage chamber is closed.
积聚
这款PMO加号独特的混合阀是一个高端阀门，用于处理安全性以及卫生的观点。阀塞在上下阀体和下阀体中始终平衡，无需对压力尖峰的敏感性。下座椅和上部座椅可由Thinktop®和轭安装的外部传感器定位。
