China Manufacture Big Size/Dimension Cast Steel Gear Box Gate Valve

    The wedge gate valve can withstand high pressure because the sealing surface of the valve is at a certain angle with the vertical centerline, and the sealing is better. Under normal circumstances, the valve stem of the wedge gate valve has been quenched and tempered and surface nitriding treatment, which has good corrosion resistance and scratch resistance; the seal of the gate and the valve seat is made of hard alloy surfacing, which is wear-resistant and high-temperature resistant. , Corrosion resistance, good scratch resistance, long service life; complete valve body materials, packing and gaskets are reasonably selected according to actual working conditions or user requirements, and can be suitable for various pressure, temperature and medium working conditions; generally available Withstand pressure can reach PN16, widely used in power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields, especially in the power station ash removal and coal washing plant equipment to play a huge role!
