    Features of stainless steel pneumatic gate valve:

    1. The materials are carefully selected, complying with relevant domestic and foreign standards, and the overall quality of the materials is high.

    2. Comply with the requirements of advanced domestic and foreign standards, with reliable sealing, excellent performance and beautiful appearance.

    3. The pairing of sealing pairs is advanced and reasonable. The sealing surfaces of the gate and valve seat are made of Stellite cobalt-based carbide surfacing with different hardnesses. The sealing is reliable, high hardness, wear-resistant, high-temperature resistant and corrosion-resistant. , good scratch resistance and long life.

    4. The valve stem has been tempered and surface nitrided, and has good corrosion resistance, scratch resistance and wear resistance.

    5. It adopts wedge-type elastic gate structure, with thrust bearings of medium and large diameters, which has low friction, and is equipped with an impact manual, making it easy to open and close.

    6. The flow direction of the medium is completely unrestricted, without disturbing the flow or reducing the pressure. The medium can flow in any direction from both sides of the gate valve, and the purpose of use can be achieved. It is especially suitable for pipelines in working conditions where the flow direction of the medium may change. middle.
