How to distinguish cast valve from forged valve？（2）
Two, forging valve 1, forging: is the use of forging machinery to apply pressure on the metal billet, so that it produces plastic deformation to obtain a certain mechanical properties, a certain shape and size of forging processing method. 2. One of the two major components of forging. Through f...Read more -
How to distinguish cast valve from forged valve？（1）
Casting valve is cast into the valve, the general casting valve pressure grade is relatively low (such as PN16, PN25, PN40, but there are also high pressure, can be 1500Lb, 2500Lb), caliber most are more than DN50. Forged valve is forged out, generally used in high grade pipeline, caliber...Read more -

Introduction of Bellows Sealed Ball Valve
Introduction of Bellows Sealed Ball Valve 1 overview Bellows-sealed valves are mainly used in harsh occasions with flammable, explosive and toxic conditions. The dual functions of packing and bellows achieve valve stem sealing, achieving zero leakage between the valve and the outside world. Bec...Read more -
What is an inverted seal gate valve?
What is an inverted seal gate valve? An inverted seal gate valve means that there is a sealing surface in the middle of the valve stem and a sealing seat inside the bonnet. When fully opened, they come in contact with each other to play a sealing role, reduce fluid erosion to the packing, and e...Read more -
Features and applications of flat gate valve
Features and applications of flat gate valve 1. Purpose, performance and characteristics The flat gate valve is a member of the large family of gate valves. Like the wedge gate valve, its main function is to control the on and off of the pipeline, not to adjust the flow of the medium in the pipe...Read more -
The function and classification of check valves
Check valve is to rely on the flow of the medium itself and automatically open and close valve disc, used to prevent the media flow back valve, also known as check valve, one-way valve, countercurrent valve, and back pressure valve. Check valve action Check valve is a kind of automatic va...Read more -
The application of check valve
The purpose of using check valves is to prevent the flow of the medium, generally in the export of the pump to install check valves. In addition, check valves should be installed at the outlet of the compressor. In general, check valves should be installed in equipment, units or lines to pr...Read more -
