The main structure features include:
resistance is small;
seat, fire safe, antistatic design;
limitation on the flow direction;
valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;
loaded packing can be chosen;

extended design can be chosen;
to metal seat design can be chosen;
,DIB-1,DIB-2 structure can be chosen;
ball is fixed with a supporting plate and a fixed shaft;
