Price comparison of butterfly valve and gate valve? The butterfly valve and the gate valve are different, but when the butterfly valve is used to cut off the medium flow in the pipeline, this function is the same as the gate valve in use. Therefore, some people have such questions when purchasing the valve, and also do the truncation. What should I choose for the butterfly valve and the gate valve? Compared with the price of butterfly valve and gate valve, which is more advantageous and cheaper?
Under normal circumstances, under the same material, diameter and specifications, the structure of the butterfly valve is simpler, the volume is smaller, and the material is also less. Compared with the gate valve under the same conditions, the price is lower and more advantageous. However,here to remind everyone, can not simply compare the price of butterfly valves and gate valves for valve selection, in practical applications, or according to the actual working environment, the needs of engineering design to do the choice. Under the same material, diameter and specification, if the diameter is below 400mm, the most expensive is the flanged butterfly valve, followed by the gate valve, and finally the wafer-type butterfly valve. When the caliber exceeds 400mm, the price of the gate valve is the most expensive, followed by the flanged butterfly valve, and the flanged butterfly valve is more suitable for the large-diameter valve. In the working environment with a diameter of less than or equal to 400mm, gate valves and wafer-type butterfly valves can be used, depending on the site conditions.
In general, when it comes to truncating the use of small-diameter pipes, the use of gate valves is recommended because the sealing performance of gate valves is better than that of butterfly valves and their service life is longer. When the pipe diameter exceeds 800mm, it is recommended that you use the butterfly valve, because the butterfly valve is more suitable for large diameter, because one is that the price of the butterfly valve is lower and the cost is lower; Second, the operation of the butterfly valve is more labor-saving than the gate valve.
However, gate valves can also be used if required by the purchase.
Through the above introduction, I believe that you have a certain understanding of the price of butterfly valve and gate valve. From the article we can see that in the selection of the valve, we can not blindly look at the price, we must choose according to the actual conditions. If you are confused about the selection of butterfly valve and gate valve products, you can inquire about the valve, like the Bundor will provide you with professional product selection guidance.
