Product overview

       The stem opening or closing stroke of the forged steel internal thread and socket welding globe valve is relatively short, and has a reliable cutting function. During the opening and closing process, due to the friction between the disc and the valve body sealing surface, the friction is smaller than that of the gate valve, so it is wear-resistant. The opening height is generally only 1/4 of the diameter of the valve seat channel, so it is much smaller than the gate valve. Usually, there is only one sealing surface on the valve body and valve disc, which is easy to maintain, and the stop valve should be selected on the pipeline or device of high temperature and high pressure media. Such as thermal power plant, nuclear power plant, petrochemical system of high temperature, high pressure pipeline, can also be applied to water, steam, oil, nitric acid and other media.
