Advantages of gate valves

1. Small flow resistance. The internal medium channel of the valve body is straight, the medium flows in a straight line, and the flow resistance is small.
2. It is less labor-saving when opening and closing. It is compared with the stop valve, because whether it is open or closed, the movement direction of the gate is perpendicular to the direction of medium flow.
3. Large height and long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lifting and lowering is performed by a screw.
4. The phenomenon of water hammer is not easy to occur. The reason is the long shutdown time.
5. The medium can flow in any direction on both sides, making it easy to install. The two sides of the gate valve channel are symmetrical.
6. The structural length (the distance between the two connecting end faces of the shell) is small.
7. Simple shape, short structural length, good manufacturing process, and wide application range.
8. Compact structure, good valve rigidity, smooth passage, small flow resistance, stainless steel and hard alloy sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation.
