Extension rod ball valve can be directly buried underground, need not build high large valve well, only need to set up small shallow Wells on the ground, greatly reduce the construction cost and project time.Can be adjusted according to the requirements of the pipeline construction and design, the length of the body and the height of the valve stem.Sphere of machining accuracy is very precise and convenient operation, no bad

Working principle:

    Extension rod ball valve consists of valve body and carbon reinforced fluorine long seal, can be in frequent operation, impurities and chemicals under the condition of long life.Fine grinding stainless steel ball can ensure that open and close freely for many years, reliable operation.Are structure of trunnion mounted ball, cant elastic guarantee seal compression on a sphere, even in the case of pressure is not stable, the valve can guarantee closely.The valve stem leakage protection structure with two "O" type circle, freely to rotate the valve stem and seal tightly.Directly buried type extension rod ball valve can be directly buried underground, need not build high large valve well, only need to set up small shallow Wells on the ground, greatly reduce the construction cost and project time.Can be adjusted according to the requirements of the pipeline construction and design, the length of the body and the height of the valve stem.Sphere of machining accuracy is very precise and convenient operation, no harmful interference.Compared with similar industry of the same specification products, the body is small, and beautiful.And can prevent the risk of gas explosion, it is very safe.Directly buried type ball valve drive, the operator does not need to enter the underground, simply on the ground for transmission operation, very safe and convenient.

Product features:
    1, the valve stem can be based on user specific installation is longer, so that the ground operation.
    2, compared with the same specification of the conventional ball valve has a small volume, light weight, good appearance, durable wait for an advantage.

    3, the valve seat sealing surface material using medium under different choice of PTFE, nylon, alloy steel, hard alloy, etc., can be wide range to adapt to different temperature, pressure and corrosion resistance.
