How to choose gate valve products

Today, the professional gate valve manufacturer in Tanghai wants to share with you: Which one is better to choose between threaded gate valve and flanged gate valve? Threaded gate valve and flanged gate valve are common

products in our daily use. Threaded gate valve is also called threaded gate valve. The biggest difference between it and flanged gate valve lies in the connection method. So to figure out whether to choose a threaded gate valve or a flanged gate valve, we only need to be clear about the factors that determine our connection method, so that it is easy to make a choice.
Generally speaking, the pressure and diameter of the pipeline have the greatest influence on the choice of connection. For gate valve products, threaded valves are used for DN80 and below, and flanged valves are used for DN80 and above valves. Sometimes flange connection is combined with threaded connection and welding connection, depending on the specific working conditions.
According to pressure conditions, flange gate valves are generally selected for high-pressure pipelines, and threaded gate valves are used for low pressure. Flange gate valves are stable and reliable when used in pipelines, so flange gate valves are often used in high-pressure pipelines. In summary, when the pressure is small, the pipe diameter is small, use threaded gate valve, and when the pressure is large, the flange gate valve is used when the pipe diameter is large.
Because flanged gate valves need to be welded to the pipeline, sometimes the material of the pipeline needs to be

taken into consideration. The flanged gate valve should be selected when the pipe material is suitable for flange welding. If the pipe material is not suitable, other connection methods need to be considered. In addition, there are many kinds of flange materials, so you can listen to the manufacturer’s suggestions according to your own pipeline conditions.
When purchasing gate valves, users should make a simple understanding of the gate valve products and their connection methods from the manufacturer. In this way, when the manufacturer makes a recommendation, the purchaser will have a concept in mind, so as to choose the gate valve product that is more in line with the budget and adapts to the working conditions.
