    介绍

    overview

    The electric gate valve is suitable for the nominal pressure PN1.6 ~ 16.0 MPa,and the working temperature is - 29 ~ 550 degrees centigrade.chemical industry,hydropower and thermal power plant all kinds of the pipeline system, cut off or connect pipe medium.Applicable medium: water, oil, steam, and acid, alkali, ammonia, urea, sulfur-containing natural gas, etc.Operation mode: manual, gear drive, electric, pneumatic, etc

    Structure and characteristics:
    1. well-selected materials, in line with the relevant standards at home and abroad, the materials of high quality in an all-round way.
    2.seal pair of advanced and reasonable, the disc and seat sealing surface with different hardness division is set (Stellite) cobalt-based hard alloy surfacing and become, reliable sealing, high hardness, wear resistance, high temperature resistance, good corrosion resistance, abrasion resistance, long service life.

    1. conform to the requirements of domestic and international advanced standard, reliable sealing, excellent performance, beautiful appearance.
      4.the valve stem through surface nitriding treatment and conditioning, with good corrosion resistance, abrasion resistance and abrasion resistance.
      5.can be used in a variety of piping flange standards and flange sealing surface forms, can meet the needs of all kinds of engineering and the user requirements.

    6.adopting the wedge gate structure, large diameter setting thrust bearing, friction small, with the impact of manual, easy opening and closing.
