Features of electric flange butterfly valve
1. D941H 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.
6. The service life of the valve with metal seal is generally longer than that with elastic seal, but it is difficult to achieve complete seal.
7. The metal seal can adapt to higher working temperature, while the elastic seal is limited by temperature.
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:
Electric flange butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power station.
Packing: wooden case, wooden pallet or packing method specified by customers.
Price： The price is changing because of material cost and exchange rate. Please give me your contact information, I will update the newest price to you
