1. Small flow resistance.
The internal medium channel of the valve body is straight through, the medium is flowing in a straight line and the flow resistance is small. 2. It is more labor-saving when opening and closing.
is compared with the cut-off valve, because whether it is open or closed, the direction of the gate movement is perpendicular to the direction of the media flow. 3. Large height, long opening and closing time.
The opening and closing stroke of the gate is larger, and the take-off and landing are carried out by screw rod. 4, water hammer phenomenon is not easy to produce.
The reason is that the shutdown time is long. 5, the media can flow to both sides in any direction, easy to install.
Both sides of the gate valve channel are symmetrical.
6. The length of the structure (the distance between the two connecting sides of the shell) is small.
7, the shape is simple, the structure length is short, the manufacture craft is good, the application scope is wide. 8, compact structure, good valve rigidity, smooth channel, small flow resistance, dense cover using stainless steel and cemented carbide, long service life, using PTFE filler, sealed reliable, flexible operation.
