American standard globe valves and flange globe valves belong to the same type of valve, and the closing part is a valve disc. The valve stem rotates around the centerline of the valve body to achieve opening and closing.

How to maintain high temperature and high pressure valves, ten major measures: 1. Use lubricating grease for lubrication. Lubricating grease should be compatible with metal materials, rubber parts, plastic parts, and working media of high-temperature and high-pressure valves. When the working medium is gas, lubricating grease such as Te221 can be used. Apply lubricating grease on the surface of the installation groove of the sealing element, apply lubricating grease on the rubber sealing elemen

Leakage of high and medium pressure butterfly valves is a common problem, but in some important system equipment, leakage of high and medium pressure butterfly valves can affect industrial production and, in severe cases, endanger the safety of people's lives and property. The high and medium pressure butterfly valves in power plants are connected to the main and auxiliary equipment and systems, and their importance is self-evident. The following is an analysis of several treatment methods for l

Different types of valves are used in different locations, and gate valves are mostly used in industrial settings. So, what is the function and working principle of the gate valve? Let's take a closer look.

1. When the double seat regulating valve is in a small opening working state, it is prone to oscillation? The reason why a double seat regulating valve cannot be used with a small opening is determined by its valve seat structure. The double regulating valve has two valve cores. The upper valve core is in the flow open state, and the lower valve core is in the flow closed state. When the valve core of the regulating valve is in the flow open state, the stability is relatively good. Therefore, w
