    Product characteristics

    1. Ultra-short structure length, saving material, can greatly reduce the overall weight of the pipeline system.

    2. It occupies less effective space, can effectively support the strength of pipeline, and can reduce the possibility of pipeline vibration.

    3. The use of austenitic stainless steel for gate can greatly improve the corrosion resistance and effectively prevent seal leakage caused by gate corrosion.

    4. Flexible PTFE is used as upper sealing filler, which is reliable and easy to operate.

    5. The gate has the function of the gate cutter and can effectively break all kinds of impurities in the medium.

    6. If the valve is made of hard sealed stainless steel and the disc is spray welded, the temperature and pressure requirements of the valve can be well expanded.
