Sutiable Media： Water， Oil，Gas
1. Low flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, flow resistance is small.
2, the opening and closing time is less effort. Is compared with the globe valve, because whether open or close, the gate motion direction and the medium flow direction are perpendicular.
3. High height and long opening and closing time. The opening and closing stroke of the gate is large, and the lifting is carried out by screw.
4, water hammer phenomenon is not easy to produce. The reason is the long shutdown time.
5, the media can flow in any direction on both sides, easy to install. Gate valve channels are symmetrical on both sides.
6. The length of the structure (the distance between two connecting end faces of the shell) is small.
7. Simple shape, short structure length, good manufacturing process, wide application range.
8. Compact structure, good rigidity of valve, smooth channel, small flow resistance, sealing surface of stainless steel and hard alloy, long service life, PTFE packing, reliable sealing, light and flexible operation.
The sealing surface is easy to cause erosion and abrasion, so it is difficult to maintain. The external size is large, it needs certain space to open and close, and the opening and closing time is long. The structure is more complex.
