1, small flow resistance. Inside the valve body, the medium passage is straight through, the medium flows in a straight line, and the flow resistance is small.
2, when opening and closing more effort. In comparison with the cut-off valve, the gate movement direction is perpendicular to the direction of the flow of the medium whether it is open or closed.
3, high height, long opening and closing time. The opening and closing stroke of the ram is larger, and the reduction is done by screw.
4, water hammer phenomenon is not easy to produce. The reason is that the shutdown time is long.
5, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.
6 、 the length of the structure (the distance between the two connecting ends of the shell) is smaller.
7. The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide.
8. Compact structure, good rigidity of valve, smooth channel, small flow resistance, stainless steel and carbide alloy used in sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation
