Introduction of imported electric hard seal butterfly valve products:

Locke imported electric hard sealing butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, food, medicine, light textile, paper making and other industries. It can be installed in industrial pipe network with temperature ≤ 425 ℃ and its medium can be gas, air, steam, water, sea water, oil and other industrial pipe network for regulating flow and cutting off medium. Electric hard seal butterfly valve with electric actuator can realize remote control and automatic operation. Electric multi-level metal seal butterfly valve series products, a long life, energy-saving butterfly valve. Its structure adopts three-dimensional core principle design, and the valve seat adopts multi-level structure compatible with hard and soft seal, with exquisite processing and advanced technology. This product is composed of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other main parts.

Features of imported electric hard seal butterfly valve:

1. Small opening torque, flexible and convenient, labor saving and energy saving.

2. The three-dimensional core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable without leakage.

3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.

4. Reasonable design, compact structure and quick opening and closing.

5. Small opening torque, friction free rotation of sealing pair and long service life of valve.

6. The replacement of valve body material and sealing ring composite interlayer can be applied to different media.
