1) The internal medium channel of the fluid resistance small gate valve body is straight through, and the flow direction is not changed when the medium flows through the gate valve, thus the flow resistance is smaller.
2) The movement direction of the gate is perpendicular to the flow direction of the medium when the opening and closing are more efficient than the other, and the gate valve's opening and closing are more efficient;
3) Medium flow direction is generally not restricted medium can flow from the gate on both sides of any direction, it can achieve the purpose of connected or truncate,easy to install, suitable for medium may change the direction of current flow in pipeline;
4) Sealing surface wear small gate valve body is equipped with guide mechanism,can prevent the disc rotate in open or closed, to ensure that corresponding alignment on sealing surface, and make the disc in the closed position has not been achieved before no friction with the valve seat, thereby reducing the wear of sealing surface;
5) The structure of simple gate valve is relatively simple, the manufacturing process is better and the structure length is shorter.
6) The packing chamber is equipped with vacuum seal structure, which has self-expanding pressure and compaction, and sealing with high pressure expansion material, so that the system is completely isolated from the atmosphere, and has a good system gas seal.
