Overview of electric flange butterfly valve:
1. D971H electric flange butterfly valve is simple in structure, small in volume and light in weight, and only consists of a few parts.
2. The valve can be quickly opened and closed by 90 ° rotation, and the operation is simple. At the same time, the valve has good fluid control characteristics.
3. When the electric flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop through the valve is very small, so it has good flow control characteristics.
4. The electric flange butterfly valve has two sealing types: elastic seal and metal seal.
5. For elastic sealing valve, the sealing ring can be inlaid on the valve body or attached around the butterfly plate. The switch value can be adjusted directly by inputting 220 V power supply, and the adjustment module can be installed. The operation can be controlled by inputting control signal (4-20 mA DC or 1-5 V DC) and single-phase power supply.
be careful:
If the electric flange butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve. The structure principle of butterfly valve is especially suitable for making large diameter valve.
Application:
It is widely used in oil pipeline, gas, chemical industry, water treatment, thermal power station and other general industries.
