Finding and selecting the best supplier is an essential first step to choosing the right water pump for your vehicle. There are many ways to find supply sources, from asking around in the industry to online research. It is an investment that requires you to consider many factors. If you choose the wrong option, then …
Reasons for slow action of pneumatic butterfly valve actuator: Insufficient air source pressure: Increase the air source pressure and set up an air storage tank on the way to reduce pressure fluctuations. The flow is not enough or other devices with large air consumption are working at the same time. Add air storage tank and …
We occasionally see relatively large valves in some pipelines and always install bypass valves. Why is this? What is its main function? Under what circumstances does it need to be installed? And what is the size of the bypass valve of the corresponding equipment? In fact, the bypass valve is installed in the pipeline, and …
As the name implies, the pressure of the valve refers to the pressure that the valve can withstand, that is, the pressure level of the valve is not lower than the design pressure level of the pipeline. The pressure-bearing direction refers to the closed state of the valve after the valve is applied to the …
As one of the most common valves in pipelines, the electric butterfly valve is used to realize the on-off of various media in the pipeline system and the control of the flow rate. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. application. Then in the commonly used …
Last weekend, COVNA team went to the group travel in Qingyuan, Guangdong Province, as the award for the winners in the last season competition. This is the first time that we travel since the beginning of the Corona Virus. We had so much fun!And we also had some interesting group activities and realized the significance …
Butterfly valves can be divided into offset plate type, vertical plate type, inclined plate type and lever type according to the structure. According to the sealing form, it is divided into two types: relatively sealed type and hard sealed type. Soft seal butterfly valves generally use rubber ring seals, and hard seal butterfly valves generally use metal …
In the daily use of valves, various failures are often encountered. Valve leakage is the most common of many failures, and valve leakage generally includes internal leakage and external leakage! So, what is the difference between the two? The internal leakage of the valve generally refers to the situation that the medium is still flowing …
Pneumatic film three-way control valve can be divided into two modes of action: converging and splitting. The spool structure adopts a cylindrical thin-walled window and is guided by the side of the spool. In some cases, it can replace two two-way valves and a three-way connection. But it is widely used, and it is often …
The biggest difference between an electric shut-off valve and a pneumatic shut-off valve, as the name suggests, is that the drive form is different, one is controlled by the power source, and the other is controlled by the air source. From the perspective of running time, the action of pneumatic valves is relatively faster, while …
