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...

Pneumatic ball valves are usually composed of electric actuators and valves. With electric energy as the power, connect the electric actuator to drive the valve to realize the switching and regulating function of the valve, so as to switch or regulate the pipeline medium. The motor of the electri...

For sheet extrusion / centralized water supply, the vacuum degree of sheet extruder is generally required to be above – 100KPA, which can meet the use requirements. On this basis, the higher the vacuum degree, the better the sheet quality. If the vacuum degree is not reached, it will cause ...

To prolong the service life of pneumatic ball valve, we should not only pay attention to its maintenance, but also pay attention to the quality of air source. The quality of air source is a very important factor affecting the service life of pneumatic valves. Therefore, the quality of gas source ...

Ball valve is a typical stop valve with high accuracy of function, and the realization of effective adjustment of the direction and size of air flow in vacuum environment is the standard that its function must meet. As a ball valve product used under vacuum conditions, vacuum ball valve not only ...

We are no stranger to the installation of pneumatic ball valve. The editor has also introduced many contents in this regard before, but there are still some users who make mistakes in installation or use it less than ideal after installation. Next, I will introduce some tips for installing pneuma...
