Uniqueミックスプルーフ・バルブのコンセプトは、幅広い用途に対応するバルブボディ、バルブプラグ、アクチュエータ、洗浄オプション、付属品などの一連の基本コンポーネントをベースにしています。 これらのコンポーネントを使用すると、お客様はプロセス要件にぴったり合ったUniqueミックスプルーフバルブを構築できます。

また、メンテナンスを容易にするために、Uniqueミックスプルーフには、静的なOリングの摩耗や損傷を事前に知らせる漏れ検知穴があります。 オペレーターは、バルブを分解することなくいつでも視覚的に検査することができます。


アルファ・ラバルのUnique ミックスプルーフバルブは、圧縮エアによって圧縮エアによって遠隔操作される常時閉(NC)バルブです。

2つの液体を分離するために、バルブには2つの独立したプラグシールがあります。2つのシールの間の空間は、漏洩チャンバーを形成します。 不測の製品漏洩が発生した場合には、これが漏洩チャンバーへ流れ込み、漏洩出口を通じて排出されます。

バルブが開いている間、漏洩チャンバーは閉じています。 1 つのラインからべつのラインへ、漏れずに流すことができます。 バルブは、特定のプロセス要件およびバルブ構造によって、容易に洗浄したりウォーターハンマーの影響から保護することができます。 (バルブ作動中の漏出はありません)。
