Butterfly Valve And Gate Valve Difference
Butterfly valve and gate valve are both important valves in pipeline fluid control engineering, both have a very wide range of uses, both in the use of the function of similar places, but butterfly valves and gate valves still have a lot of differences, the most intuitive difference lies in the appearance of the difference, this article by DELCO Valve for you to introduce more difference between butterfly valves and gate valves.
What is a butterfly valve
Butterfly valve, also known as flap valve, is a simple structure of the regulating valve, can be used for low-pressure pipeline media switching control of the butterfly valve is the closing member (valve flap or butterfly plate) for the disk, rotating around the valve axis to achieve the opening and closing of a valve.
What is a gate valve
Gate valve, its opening and closing member is called the gate, the gate with the valve stem to do lifting movement to achieve the opening and closing of the valve, the gate of the valve gate movement direction and the direction of the circulating medium in the valve body is perpendicular to the direction. Gate valve can only be fully open or fully closed, in the pipeline can only do to cut off the flow of media to use. When the gate valve is fully open, the fluid resistance in the valve body is less than the butterfly valve.
Difference Between Butterfly valve and gate valve
Structural differences
- Butterfly valve body has a butterfly plate, the butterfly plate through the rotation to control the flow of fluid;
- The gate valve has a gate, which controls the flow of fluid by lifting.
Difference in the way of action
- Gate valve belongs to the straight stroke valve, that is, the valve stem drives the valve plate to do up and down vertical movement, to complete the opening and closing of the gate valve, so the gate valve flow resistance is small, but because of its high opening height, so the opening and closing speed is slow.
- Butterfly valve belongs to the angle stroke valve, that is, the butterfly valve valve plate around the valve shaft to do 90 ° rotation, to complete the butterfly valve opening and closing action. Therefore, the opening height of butterfly valve is only one quarter of the diameter of the channel, so it opens and closes quickly.
The difference of applicable working conditions
- Gate valve flow resistance is small, good sealing performance, because the gate valve plate and the media flow direction is vertical angle, if the gate valve in the valve plate switch is not in place, the media on the valve plate scouring the valve plate trembling, it is very easy to shine into the gate valve seal damage. Therefore, more for the requirements of strict sealing and do not need frequent opening and closing of the pipeline to do cutoff, but not suitable for the role of regulating the pipeline media parameters. Because the opening and closing speed is slow, also does not apply to emergency cut off occasions. Gate valve use a wide range of conditions, in high temperature, low temperature, high pressure, low pressure and other conditions can be used.
- Butterfly valve not only has the role of cut-off, and has the function of regulating. Butterfly valve open and close quickly, can be opened and closed frequently, in the requirements of rapid opening or cutting off the occasion is particularly suitable. Relative to the gate valve butterfly valve small size, light weight, cheap, in some limited installation space conditions, you can choose the butterfly valve clamped connection, more space-saving. So it can be made into a large caliber, dn300 or more butterfly valves are used more. And can be used for the transportation of small particles containing unclean media pipeline. But the pressure and temperature range of butterfly valve is small, and the sealing performance is not as good as gate valve. The same caliber butterfly valve price is much lower than the gate valve.
Conclusion
Butterfly valves and gate valves are common fluid control valves, but as the article introduces, butterfly valves and gate valves in some aspects there are obvious differences.
