Advantages of gate valves

As a Advantages of gate valves

1, low flow resistance. JIS marine gate valve body internal medium channel is through, medium into a straight line flow, flow resistance is small.

2, the opening and closing is easier. Is compared with the globe valve, because whether it is open or closed, the movement direction of the gate is perpendicular to the media flow direction.

3, high height, long opening and closing time. The opening and closing stroke of the gate is large, and the drop is carried out through the screw.

4, water hammer phenomenon is not easy to produce. The reason is the long shutdown time.

5, the media can flow to both sides of arbitrary direction, easy to install. Gate valve channels are symmetrical on both sides.

6, the length of the structure (the distance between the two connecting end faces of the shell) is small.

7, JIS gate valve has simple form, short structural length, good manufacturing, wide range of application.

8, compact structure, good rigidity of valve, smooth passage, small flow resistance, sealing surface is made of stainless steel and hard alloy, with long service life and PTFE filler. Reliable sealing. The operation is light and flexible.
