1, small flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.
2, less effort when opening and closing. It is compared with the globe valve, because whether it is open or closed, the direction of the ram movement is perpendicular to the direction of the medium flow.
3, high height, long opening and closing time. The opening and closing stroke of the gate is large, and the fall is carried out by the screw.
4, water hammer phenomenon is not easy to produce. The reason is the long shutdown time.
5, the medium can flow to either side in any direction, easy to install. Both sides of the gate valve channel are symmetrical.
6, the structure length (the distance between the two connected end faces of the shell) is small.
7, simple shape, short structure length, good manufacturing process, wide range of application.
8, compact structure, good valve rigidity, smooth channel, flow resistance number is small, sealing surface is made of stainless steel and carbide, long service life, PTFE packing. Reliable seal. Light and flexible operation.
