Features of manual stainless steel ball valves

Date:Aug 26,2016

Stainless steel electric ball valve is it has the same rotation of 90 degrees to lift the action, there is a circular through hole or channel through its axis. The ratio of the spherical surface and the channel port should be such that when the ball is rotated 90 degrees, the inlet and outlet should be all spherical, thereby cutting off the flow.

Stainless steel electric ball valves only need to use gas to rotate 90 degrees of operation and a small torque can be closed tight. Full equality of the inner cavity of the valve body to provide a very small resistance, through the flow channel. It is generally considered the most suitable for the use of open and close, but the recent development has been designed to make it with the throttle and control flow. The main features of the valve is itself has the advantages of compact structure, easy operation and maintenance, applicable to water, solvents, acids, and natural gas and other general working media, but also applicable to the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve can be a whole, but also can be a combination of.

Features of manual stainless steel ball valve:

Ball valve is mainly used to cut off or connected to the media in the pipeline, also can be used for the adjustment and control of fluid, it has the following advantages compared with other valves.

1. Fluid resistance is small, ball valve is the smallest of all types of fluid resistance, even if it is a ball valve, the fluid resistance is also very small.

2. Thrust bearings to reduce the friction torque of the stem, can make the long-term operation of the valve stem smooth and flexible.

3. The sealing performance of the valve seat is good, the sealing ring made of the elastic material such as Teflon is easy to be sealed, and the sealing ability of the ball valve is increased with the increasing of the medium pressure.

4. Reliable stem sealing due to stem only for imitation rotation transported without doing the lifting movement, stem packing seal is not easy to destroy, and the sealing ability increased with the increase of the pressure of the medium.

5. Because PTFE and other materials with good self - lubrication, and the ball friction loss is small, so the long life of the ball valve.

6. Download stem and stem head convex order to prevent stem spray, such as stem seal damage caused by fire, convex order and the body can also form a metal contact, to ensure that the valve stem seals.

7. Anti static function: the ball, the stem, the valve body between the set of springs, the switch can be generated by the process of static.
