What are the differences between electric and pneumatic wafer butterfly valves
Electric wafer butterfly valves are generally used as ventilation components in chemical plants, building materials plants, power stations and other industries to regulate or cut off gas flow.
Features of electric wafer butterfly valve:
1. The valve body is small, light and convenient for installation, with small internal resistance and large flow rate.
2. There are no connecting rods, bolts and other parts inside the valve body, so the service cycle is long.
3. It is not limited by the installation position, nor affected by the flow direction of the medium in the valve body.
4. It is widely used in building materials, coal mines, power generation and other pipelines.
Pneumatic wafer butterfly valve is a conventional butterfly valve that is often and preferentially used in work. The wafer butterfly valve is a newly developed key product in China. It does not require manual operation of the switch, which greatly saves manpower and time. The implementation capacity has been improved.
Features of pneumatic wafer butterfly valve:
1. The three eccentric sealing structure is adopted, and the friction between the butterfly plate and the valve body base is negligible, so it can achieve the sealing effect of almost complete sealing.
2. The sealing surface of the butterfly plate is made of special alloy material, which greatly improves the wear resistance and prolongs the service time of the valve body.
3. Double sealing rings made of stainless steel are adopted, which are not affected by temperature changes.
4. The internal resistance of the valve body is small, the fluid area is increased, and is not affected by the fluid direction.
5. The driving device can be adjusted according to the actual situation.
6. Widely used, such as building materials, coal mines, water and electricity, gas and other pipelines.
