Como funciona


O conceito da válvula Unique Mixproof é baseado em uma série de componentes de base, incluindo o corpo da válvula, plugue da válvula, atuador, opções de limpeza e acessórios que suportam uma ampla gama de aplicações. Usando esses componentes, você pode criar uma válvula Unique Mixproof para atender aos requisitos exatos do processo.

Para facilitar a manutenção, a válvula Unique Mixproof também possui orifícios de detecção de vazamento que fornecem notificação antecipada de desgaste ou danos nos O-rings. Os operadores podem inspecionar visualmente a válvula a qualquer momento sem precisar desmontá-la.

Princípio de funcionamento

A válvula Alfa Laval Unique Mixproof é normalmente fechada (NC) e controlada diretamente de um local remoto por meio de ar comprimido.

Para separar os dois líquidos, a válvula possui duas vedações de plugue independentes. O espaço entre as duas vedações forma uma câmara de vazamento atmosférico. No caso raro de vazamento acidental do produto, o produto flui para a câmara de vazamento e é descarregado através da saída de vazamento.

Quando a válvula estiver aberta, a câmara de vazamento estará fechada. Dessa forma, o produto pode circular de uma linha para a outra sem derramamentos. A válvula pode ser facilmente limpa e protegida contra efeitos de golpe de aríete de acordo com os requisitos específicos do processo e a configuração da válvula. (Não há derramamento de produto durante a operação da válvula.)

SpiralClean system

Alfa Laval offers its external connected CIP system "SpiralClean". This system ensures hygienic operation in demanding applications where cleaning of the Unique Mixproof by seat lift and seat push function is not sufficient. The SpiralClean system can be added to clean the upper and lower plugs and to rinse the leakage chamber of the valve. Using less cleaning fluid, utilities and time, SpiralClean cleans more thoroughly and efficiently than conventional externally connected CIP devices.

Another big benefit: SpiralClean enables the Unique mixproof valve to operate under aseptic-like conditions, creating a steam barrier to the atmosphere upon applying steam to the CIP pipes.unique-mixproof-spiral-clean-640x360.png
