Gate valve Features:

(1) The flow resistance is small. The inner medium passage of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

(2) It is more labor-saving when opening and closing. Compared with the shut-off valve, the direction of movement of the ram is perpendicular to the direction of flow of the medium, whether it is open or closed.

(3) The height is high and the opening and closing time is long. The opening and closing stroke of the shutter is large, and the drop is performed by the screw.

(4) The water hammer phenomenon is not easy to come. The reason is that the shutdown time is long.

(5) The medium can flow in any direction on both sides, which is easy to install. The gate valve channels are symmetrical on both sides.

(6) The structural length (the distance between the two connecting end faces of the casing) is small.

(7) The sealing surface is easy to wear and affect the service life. When opening and closing, the two sealing surfaces of the gate and the valve seat rub against each other, and it is easy to cause abrasion and abrasion under the action of the medium pressure, which affects the sealing performance and shortens the service life.

(8) The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide.

(9) Compact structure, good rigidity of the valve, smooth passage, small flow resistance, stainless steel and hard alloy on the sealing surface, long service life, PTFE packing, reliable sealing, light and flexible operation.
