What should be noted when purchasing cast steel valves?

Celebrating the 70th anniversary of the founding of the People's Republic of China in 2019, we applaud the strength of our motherland and wish it prosperity and flourishing! The strong motherland not only brings happiness to our people, but also brings us more welfare and livelihood projects.

When it comes to engineering construction, many friends responsible for engineering procurement know that valves are an essential and important component of engineering construction. Besides being familiar with the manufacturer, some infrequently purchased items may not be very clear. Below, I will briefly share my personal opinions for reference only;

Firstly, when purchasing valves, important factors such as material, caliber size, medium, and pressure must be determined. Common and commonly used materials include stainless steel, cast steel, carbon steel, and molybdenum steel, among others. There are many different types of valves that can be further subdivided. Here, we would like to mainly discuss some precautions for cast steel valves.

1. The demand for cast steel valves in the market is relatively high because the raw material cost of cast steel is lower than that of stainless steel, and there are also some differences in the applicable media;

2. There are also more cast steel gate valves in cast steel valves, and the required valves vary according to the needs of pipeline circulation. The other types are cast steel ball valves, cast steel butterfly valves, cast steel globe valves, cast steel check valves, etc;

3. Some places with low pressure requirements generally choose cast steel valves or discharge of river water flow;

4. The specific caliber size should also be matched with the pipeline;

5. The specific requirements for pressure may vary depending on the region of use;

In general, those with procurement experience will avoid some detours. Whether it is cast steel valves or stainless steel valves, it is necessary to carefully check the detailed selection parameters to ensure better utilization on site.
