Carbon steel zero leakage gate valve

        Zero leakage gate valve stem is split, the stem runs stable vertical, the upper valve stem is connected with the handwheel nut. The lower valve stem adopts the structural principle of the plunger valve, the middle positioning hole frame, the upper and lower with high strength soft sealing ring, the lower inverted seal. Such a triple seal to prevent leakage of the valve, can be switched thousands of times without leakage. Products are widely used in petroleum, chemical, petroleum products, water, steam, gas, power station and other pipelines, for connecting and truncating the medium of the opening and closing device.

        1, compact structure, reasonable design, good valve rigidity, smooth channel, flow resistance coefficient is small;

        2, sealing surface using stainless steel hard alloy, long service life;

        3, the use of flexible graphite filler, reliable sealing, light and flexible operation;

        4, the driving mode is manual, pneumatic, electric, gear drive, hydraulic;

        5, the structure of the elastic wedge type single ram, rigid wedge type single ram double ram type.
