Description:

The 4 Inch Gate Valve is a shutter of the opening and closing member. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled.


Advantage:

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, high height, long opening and closing time. The opening and closing stroke of the shutter is large, and the lifting is performed by the screw.

4. The water hammer phenomenon is not easy to produce. 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 length of the structure (the distance between the two connecting end faces of the casing) is small.

7. Simple shape, short structure length, good manufacturing process and wide application range.
