Shut-off valve较之Butterfly valveThe adjustment performance is good,Butterfly valveThe adjustment performance is poor, and it is generally used in occasions where only a switch is required.on the other handShut-off valveBetter thanButterfly valveThe price is high.
Shut-off valve:versusgateIn comparison, the structure is simple, the manufacture and maintenance are convenient, the adjustment performance is good, and it is widely used in the conveying pipeline of various media.But the fluid passesShut-off valveThere are changes in direction from time to time, so the resistance is relatively large. It is not suitable for pipelines with high viscosity, suspended substances and easily crystallized materials, and also for venting valves and valves for low vacuum systems.Shut-off valveWidely used in various pressure fluid pipelines, and also commonly used in steam and compressed air pipelinesShut-off valve. Shut-off valveIt is a commonly used cut-off valve, which is mainly used to connect or cut off the medium in the pipeline. It is generally not used to adjust the flow.The globe valve is suitable for a wide range of pressure and temperature, but it is generally used for medium and small diameter pipelines.
Butterfly valve: Butterfly valve, also called flap valve, is a simple structureControl valve.Because the butterfly valve is not suitable for tightly matching with the pipe wall, it is only suitable for adjusting the flow rate, and cannot be used to cut off the pipeline. It is often used to adjust the flow rate on the pipeline that transports air and flue gas. Butterfly valveIt is a valve that uses a circular butterfly plate that rotates with the valve stem as an opening and closing part to realize the opening and closing action.Butterfly valveIt is mainly used as a cut-off valve, and can also be designed to have the function of adjustment or cut-off and adjustment.CurrentlyButterfly valveThe use of low-pressure large and medium-diameter pipelines is increasing.
