Structural features：

1. There is no friction between opening and closing.

2. Top mounted structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.

3. Single seat design. The problem that the medium in the valve cavity is affected by abnormal pressure rise is eliminated.

4. Low torque design. Special structure design of the stem, just with a small handle valve can easily open and close.

5. Wedge seal structure.

6. Self cleaning structure of sealing surface. This kind of valve should be installed horizontally on the pipeline

7. Transmission mode：Manual, electric, bevel gear

Advantage

It is mainly used to cut off, distribute and change the flow direction of medium in pipeline. Globe valve is a new type of valve widely used in recent years. It has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.

2. Simple structure, small volume and light weight.

3. It is tight and reliable. At present, the sealing surface material of gate valve is widely made of plastic with good sealing performance, and it has been widely used in vacuum system.

4. Convenient operation, fast opening and closing, from full opening to full closing as long as 90 ° rotation, convenient for remote control.

5. Easy maintenance, simple structure of gate valve, movable sealing ring, easy disassembly and replacement.

6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface.

7. It has a wide range of applications, ranging from small diameter to several millimeters, to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at the inlet and outlet, so as to cut off the flow.

Application:

in chemical equipment, food equipment, medical equipment, environmental protection equipment, water treatment equipment and other major products.
