In the many valve products, gate valves and butterfly valves are the most commonly used valve models, the following we will understand the difference between the two types of valves from several aspects.

Soft seal gate valve for sale product description

Butterfly valve: Butterfly valve belongs to angle stroke valve, that is, the valve plate of butterfly valve rotates 90 degrees around the valve axis to complete the opening and closing of the butterfly valve, so the opening height of the butterfly valve is only a quarter of the diameter of the channel, so the butterfly valve opens and closes quickly and sensitively.

Butterfly valve product description

2.Working conditions and media butterfly valve is suitable for furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold wind, chemical smelting power generation, environmental protection, building water supply and drainage and other engineering systems to transport a variety of corrosive and non-corrosive fluids on the pipeline, used to regulate and cut off the flow of media.

Gate valve is a kind of opening and closing gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, and its inclination angle of 2 ° 52'. In order to improve its craftsmanship, to make up for the deviation of the angle of the sealing surface during processing, this gate is called elastic gate.

When the gate valve is closed, the sealing surface is sealed only by the medium pressure, that is, only by the medium pressure of the sealing surface of the gate plate to the other side of the valve seat, to ensure that the sealing surface of the sealing surface of the seal, is a self-sealing. Most gate valves are forced sealing, that is, when the valve is closed, the gate must be forced by external force on the valve seat to ensure that the sealing surface of the tightness.

In many cases, butterfly valves have gradually replaced other types of valves. The main difference between gate valves and butterfly valves is that gate valves do not have an adjustment function, while butterfly valves have an adjustment function.
