Electric hard seal butterfly valve product description

The Electric hard seal butterfly valve produced by Anshan AEN.TECH is widely used in petroleum, chemical, electric power, metallurgy, food, medicine, textile, paper making and other industries. It can be installed at temperatures ≤ 425 ° C. The medium can be gas, air and steam. , water, seawater, oil and other industrial pipe network for regulating flow and cutting media. The Electric hard seal butterfly valve is equipped with an electric actuator for remote control and automation. Electric multi-layer metal sealing butterfly valve series is a long-life, energy-saving butterfly valve. The structure is designed by three-dimensional knitting principle, and the valve seat adopts a multi-layer structure compatible with hard and soft seals, with exquisite processing and advanced technology. This product consists of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other main components.

Electric hard seal butterfly valve product features

Because the Electric hard seal butterfly valve adopts the three-dimensional eccentric principle design, the space movement track of the sealing surface is idealized, the sealing surfaces have no friction and mutual interference, and the sealing material is properly selected, so that the butterfly valve is sealed and resistant. Corrosiveness, high temperature resistance and wear resistance are reliably guaranteed. Its main features are as follows:

(1) The opening torque is small, flexible and convenient, saving energy and energy.

(2) The three-dimensional braiding structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable, and no leakage is achieved.

(3) High pressure resistance, corrosion resistance, wear resistance and long service life.
