The steel fully welded ball valve is a very common valve, its main feature is that because the ball and the valve body are welded into one piece, the valve is not easy to produce leakage during use. It is mainly composed of valve body, ball, stem, seat, gasket and so on. The stem is connected to the valve handwheel through the ball, and the handwheel is rotated to turn the ball to open and close the valve. Production materials vary according to the use of different environments, media, etc., mainly carbon steel, stainless steel, alloy steel, cast steel, etc.

    Product Advantage

    Main use:
    1) City gas: gas output pipeline, main line and branch line supply pipeline, etc.
    2) Central heating: output pipelines, main lines and branch lines of large heating equipment.
    3) Heat exchanger: open and close pipes and circuits.
    4) Steel plants: various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines.
    5) Various industrial equipment: various heat treatment pipes, various industrial gas and heat pipes.

    1) Fully welded ball valve, there will be no external leakage and other phenomena.
    2) The processing process of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high.
    3) Since the material of the valve body is the same as that of the pipeline, there will be no uneven stress and no deformation due to earthquakes and vehicles passing the ground, and the pipeline is resistant to aging.
    4) The body of the sealing ring is made of RPTFE material with a content of 25% Carbon (carbon) to ensure no leakage (0%).
    5) The directly buried welded ball valve can be directly buried in the ground, without the need to build high and large valve wells, only need to set up small shallow wells on the ground, which greatly saves construction costs and engineering time.
    6) The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
    7) The machining accuracy of the sphere is very precise, the operation is light, and there is no adverse interference.
    8) The use of advanced raw materials can ensure the pressure above PN25.
    9) Compared with products of the same specification in the same industry, the valve body is small and beautiful in appearance.
    10) Under the condition of ensuring the normal operation and use of the valve, the service life is more than 20 years.
