1.Bellow seal element. The key part of bellow sealed globe valves is mental bellow. 

It is the connection between cover and stem with automatic roll welding. The mental bellow can keep the 

stem part no leakage.

2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.

3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.

4.Grease nipple. It can direct lubricate the stem, nut and sleeve.

5.Ergonomic hand wheel. It provide longer service life and easier operation.


The opening and closing part of the stop valve (Globe Valve) is a plug-shaped valve disc with a flat surface or 

a sea cone on the sealing surface, and the valve disc moves linearly along the center line of the valve seat. The 

movement form of the valve stem, (common name: dark stem), also has a lifting and rotating rod type, which 

can be used to control various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid 

metal, and radioactive media. flow. Therefore, this type of shut-off valve is very suitable for shutting off or 

regulating and throttling. Since the opening or closing stroke of the valve stem of this type of valve is relatively 

short, and it has a very reliable cut-off function, and because the change of the valve seat port is in direct 

proportion to the stroke of the valve disc, it is very suitable for flow adjustment.
