Maintenance of Stainless Steel Ball Valve

Jan. 22, 2020

The stainless steel Ball Valve can be closed tightly with only 90 degrees of rotation and a small torque. The completely equal valve body cavity provides a low resistance, straight flow channel for the medium. The main feature of the ball valve is its compact structure, easy to operate and maintain, suitable for general working media such as water, solvents, acids and natural gas, but also suitable for media with harsh working conditions, such as oxygen hydrogen peroxide, methane and ethylene. The ball valve body can be integrated or combined. This type of valve should generally be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve material is divided into 304,316,321 stainless steel ball valve.


Stainless steel ball valve is very easy to contact with other metal and iron products during the manufacturing process. In order to keep the stainless steel valve from rusting, the easiest way is to do the following process.

1. After the finished product, after pickling, it must be washed clean. If there are sand holes or perforations, it should be welded by gas shielded welding. Then sanding, and then solid solution treatment;

2. Finished product, after processing pressure test is completed. Rinse with water with antirust powder.

3. Use wooden case packaging as much as possible during transportation, without touching metal products.

4. After installing the pipeline, regularly maintain and maintain it, for example, the valve stem is often coated with lubricant. Properly open and close the valve several times. It is difficult to assimilate the inner ball, the valve stem and the sealing surface.

Thread Ball Valve

Stainless steel ball valves generally have two structures with reduced diameter and non-reduced diameter channels. No matter what kind of structure, the flow resistance coefficient of the ball valve is relatively small.

In particular, the so-called full-flow type, that is, a ball valve that does not have a reduced diameter, because its channel diameter is equal to the inner diameter of the pipe, the local resistance loss is only the frictional resistance of the pipe of the same length, that is, the flow resistance of this ball valve is the smallest among all valves. In the rocket launch and its test system, the smaller the resistance of the pipeline, the better. There are two ways to reduce the resistance of the piping system: one is to reduce the flow velocity of the fluid. To this end, it is necessary to increase the diameter of the pipe and the valve. This will often have an adverse effect on the economics of the piping system, especially for low-temperature delivery systems ( Liquid hydrogen) is extremely disadvantageous.

The above is the maintenance of stainless steel ball valve introduced by the Thread Ball Valve supplier. Hope to help everyone.
