Electric ball valve is an important valve class, which is widely used in petrochemical industry, long-distance pipeline and other fields. The closing part of the ball valve is a ball (or part of the ball) with a hole. The ball rolls with the valve stem to complete the opening or closing of the va...

It is forbidden to plug the plug-in box with electricity. After installation, the front and rear claw type chucks shall be fixed on both sides of the electric ball valve, and the screws shall be tightened. When the plug-in box with large-scale switch is installed vertically, the bottom shall be e...

In some special environments, the electric stainless steel explosion-proof ball valve will inevitably be worn during long-term use. Of course, the wear of its rotating spherical surface (inner ball) is mainly discussed here. Once this happens, it will often lead to large resistance during opening...

The stainless steel ball valve shall be completed in strict accordance with the required steps before and after assembly. The parts and components of the stainless steel ball valve shall be processed before assembly. The details are as follows: 1. According to the processing requirements, some pa...

The opening and closing of the valve are usually confirmed by the position of the handle. The handle is parallel to the pipeline to open the valve and vertical to close the valve. However, the connection between the handle and the valve stem of the ordinary ball valve is flat and square, which is...

How does the electric ball valve control the opening of the valve? You will understand after reading it. The flow characteristics can be linearized and can replace the old control valve; Small volume and light weight; Imported key parts and components, high reliability Genuine materials and long ...

Electric ball valve is one of the important actuators in industrial automation control system. Electric ball valve is also a valve that rotates around the valve stem axis according to the movement of the valve disc. When the electric ball valve is de energized, is the valve normally closed or rem...

During the use of the electric ball valve, the reversing speed is slow. What are the reasons for this phenomenon? If the electric ball valve is used for a long time, the reversing will be slow. The reversing of electric ball valve is not slow. The common current industrial structure is to solve ...

Leakage of explosion-proof electric ball valve often occurs on packing, flange seal and valve body. Long term leakage of the valve will lead to corrosion of the valve stem and flange sealing surface, resulting in scrapping of the electric ball valve. Consume more, increase cost and reduce economi...

For ball valves, their main functions are similar, but the differences are slight differences in properties and materials. Among many ball valves, electric ball valve is an important product. Its appearance is really helpful to production and safety. Now let’s take a look at the working pri...
