To understand the difference between globe valve and stop check valve, we should first figure out what is a stop check valve. Stop check valve combines the functions of a general globe valve and check valve, which means besides isolating and regulating the flow rate, it can also prevent reverse flow. From the appearance, globe valve and stop check valve almost look the same. The main difference li...

Compared with other mechanical manufacturing processes, the valve manufacturing process has the following characteristics: A. The manufacture and inspection technology of valve rough is very complicated. The valve's casting blank is a thin-walled shell with complicated structure. Casting requires a smooth surface, casting characters clear, especially to have a dense structure, and do not allow the...

1. What is the difference between Cast iron and Cast steel? The difference between Cast iron and Cast steel is their carbon content. Cast Iron with carbon content greater than 2.06% is iron; steel with carbon content between 0.02% and 2.06% is steel. 2. What is carbon steel? How many categories does it fall into? An alloy of carbon and iron (when the carbon content is between 0.02% and 2.06%) is c...

Bronze and brass are two of the most common materials used to produce valves. This preference comes because both metals are quite malleable. They both are artificially made from natural metallurgical elements: brass is made from copper and zinc, while another is made primarily from copper and tin. Each metal offers valves numerous and various advantages...

What is valve corrosion? Corrosion of valves is usually understood as the damage to the metal materials of the valve caused by the chemical or electrochemical environment. Since the corrosion appears in the spontaneous interaction between the metal and the surrounding environment, the focus of corrosion prevention is how to isolate the metal from the surrounding environment or more use of non...

As winter approaches, the temperature gradually drops and the valves outsides are getting greater chance tobe froze. At this time, the pipeline will easily fail if not take some acts. And when it comes to some high-risk working conditions, accidents may also occur. Therefore, the anti-freezing treatment of valves is crucial to industrial equipment. Before th...
