  • Rubber Check Valve

    Rubber Check Valve

    【Introduction】: A check valve made of wear-resistant materials
    【Opening Pressure】: 0.001Mdda
    【Improvement】: Xinhai rubber check valve is made of Xinhai 35 wear – resistant rubber with strong wear and corrosive resistance. Experiment shows that it be immersed in a concentration of 30% sulfuric acid or alkaline solutions; 48 hours later, the performance of the rubber has no obvious change, so the applicable range is very wide.

  • Y-Ball Valve

    Y-Ball Valve

    【Introduction】: One valve control two pipes.
    【Pressure】: ≤0.7MPa
    【Improvement】: Automatic control, one ball valve can automatically open and close the valve This design has obtained national patent in May 2011, patent number: ZL201020575061.8.

    One valve control two pipes.

Knife Gate Valve

Rubber spool is produced with " liquid phase nanometer compounding, normal temperature high-frequency curving". Wear-resistant index id over 128% and its service life is 2-4 times longer than ordinary valves under the same working conditions. Xinhai wear – resistant rubber as liners of knife gate valve owns high resilience up to 86% and high sealing performance, no leakage Simple structure, convenient operation and maintenance No pressure lose
