Ductile iron GGG40 knife gate valve is one kind of knife gate valve. The working principle of the DI DDD40 knife gate valve is to turn the hand wheel by man power to make the valve stem rise up and fall down, thereby driving the valve plate of the knife gate valve to move up and down to realize the opening and closing of the Ductile iron GGG40 knife type gate valves.
When we turn the hand wheel clockwise, the valve plate goes down and the DI ggg40 knife type gate valve closes. And when we turn the hand wheel counterclockwise, the plate of the DI knife gate valve rises up and the knife gate valve opens.
Compared with the traditional gate valve, the structure of the Ductile iron GGG40 knife gate valve is simpler, the length of the knife gate valve is smaller. And relatively the knife type gate valve is easier to install, disassemble, and maintain. GGG40 ductile cast iron knife gate valves are suitable for use in medium pipelines with high consistency and solid particles. The blade-like valve plate of the GGG40 knife gate valve has a better breaking effect and can effectively break all kinds of impurities in the medium of the pipeline. Completely solving the leakage phenomenon caused by the traditional gate valve when using for the medium containing particle impurities.
The structural length of the ductile iron ggg40 knife type gate valve is very short and onlt takes little installing space. The full-bore knife gate valve design allows the knife gate valve to be used in dirty media, and the replaceable seat and packing also make the ggg40 ductile cast iron knife gate valve easier to maintain.
