    Product Description

    1. Vacuum Butterfly Valve is designed for negative pressure vacuum systems, with concentric resilient seal structure and low leak rate inside valve body.

    2. Valve body and sealing surface precision machined to reduce gas leak rate, suitable for negative pressure working conditions.

    3. Used in vacuum metallurgy, vacuum coating and vacuum pump supporting pipelines.

    4. Achieves gas on off and flow regulation in vacuum pipelines.

    Features & Benefits

    1. Precision sealing surface with low gas leak rate, meeting vacuum system requirements.

    2. Double offset structure with low operating torque.

    3. Suitable for high, medium and low vacuum degrees.

    4. Smooth internal cavity reduces medium residue and outgassing.

    5. Manual, pneumatic or electric actuator optional, suitable for automated vacuum equipment.

    6. Compact structure for narrow space in vacuum equipment.
