Beijing Jiujiu Yuda Electromechanical Technology Co., Ltd.

JOJOVAC es un fabricante de válvulas de alto vacío. Las válvulas de compuerta neumáticas de alto vacío se utilizan a menudo para aislar el flujo de gas en sistemas de alto y ultra alto vacío. El aire comprimido actúa sobre el cilindro, proporcionando la fuerza necesaria para accionar la placa de la válvula y permitir su apertura y cierre.
El cuerpo de la válvula está hecho de acero inoxidable y pasa por un riguroso proceso de pulido, lo que garantiza alta rigidez estructural, funcionamiento suave y una apariencia estética. El sello del eje es un fuelle de acero inoxidable, que proporciona una larga vida útil y un buen rendimiento de sellado. Es adecuado para condiciones de trabajo donde el medio es aire o gases no corrosivos.
