Gate valve and butterfly valve are both very common valves. They are very different in their own structures, use methods, adaptation to working conditions, etc. This article will help users to better understand the difference between gate valve and butterfly valve, so as to better help users to select valves.
The gate valve can cut off the medium in the pipeline like a gate. The opening and closing parts of the gate valve are called rams. The ram moves up and down in a direction perpendicular to the flow direction of the medium in the fluid pipeline; The gate valve is a block valve, which can only be fully opened or closed, and cannot regulate the flow.
Butterfly valve, also known as flap valve. Its opening and closing part is a disc shaped butterfly plate, which is fixed on the valve stem and rotates around the valve shaft of the valve stem to realize opening and closing. The movement direction of the butterfly valve is to rotate in place. It only needs to rotate 90 ° from fully open to fully closed. In addition, the butterfly plate of the butterfly valve does not have self-locking capacity, so a turbine reducer needs to be installed on the valve stem. With it, the butterfly plate has self-locking capacity, and can also improve the operating performance of the butterfly valve.
The difference between gate valve and butterfly valve is introduced as follows:
1. Differences in sports ability
Because the gate valve can only be fully opened and fully closed, the flow resistance of the gate valve is smaller when it is fully open; When the butterfly valve is fully open, the thickness of the butterfly valve will cause resistance to the flow medium. In addition, the opening height of the gate valve is high, so the opening and closing speed is slow; The butterfly valve can be opened and closed only by rotating 90 °, so it can be opened and closed quickly.
2. Difference in function and use
Gate valves have good sealing performance, so they are mostly used in pipelines that require strict sealing and do not need to be opened and closed repeatedly to cut off the flow medium. The gate valve cannot be used to regulate the flow. In addition, because the opening and closing speed of the gate valve is slow, it is not applicable to the pipeline requiring emergency cut-off. The use of butterfly valve is relatively more extensive. The butterfly valve can not only be used for cutting off, but also has the function of adjusting the flow. In addition, the butterfly valve can be opened and closed quickly and frequently, which is especially suitable for applications requiring quick opening or closing.
 
The overall dimension of butterfly valve is smaller than that of gate valve, and its weight is also lighter than that of gate valve. Therefore, in some environments with limited installation space, it is recommended to use the wafer type butterfly valve that saves more space. Among large diameter valves, პეპლის სარქველები are used most frequently. It is also recommended to use butterfly valves in medium pipelines containing small particles of impurities.
In the selection of valves under many working conditions, butterfly valves have gradually replaced other types of valves and become the first choice of many users.
3. Difference in price
Under the same pressure and diameter, the price of gate valve is higher than that of butterfly valve. However, the diameter of butterfly valve can be very large, and the price of large diameter butterfly valve is not cheaper than that of gate valve.
The above is our distinction between gate valves and butterfly valves. WALTER brand is specialized in producing butterfly valves and gate valves for water systems. High quality, low price, welcome to purchase
