▶This valve adopts triple eccentric sealing structure, the valve seat and butterfly plate wear little.
▶The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life regardless of low temperature and high temperature.
▶The sealing surface of the butterfly plate adopts surfacing welding cobalt-based hard alloy, which is wear-resistant and has a long service life.
▶The large-diameter butterfly plate adopts the quilted frame structure, which has high strength, large flow area and small flow resistance.
▶The electric three-eccentric butterfly valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation and is not affected by the spatial position. It can be installed in any direction.
▶The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.
Pneumatic Gas Triple Eccentric Butterfly Valve
The pneumatic gas triple eccentric butterfly valve, its structure adopts three-dimensional core design principle, the triple ennectric butterfly valve seat adopts a multi-level structure compatible with hard and soft sealing, exquisite processing and advanced technology. Pneumatic triple eccentric butterfly valve can be equipped with pneumatic valve positioner, input control signal air source to control operation, and can also be equipped with stroke limit switch, solenoid valve, triple piece and 0.4-0.7MPa gas, it can realize the switch operation, and send out two pairs of passive contact signals to indicate the switch of the butterfly valve. Pneumatic triple eccentric butterfly valve is composed of main parts such as valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism, etc. The pneumatic butterfly valve is a long-life, energy-saving valve. Pneumatic triple eccentric butterfly valves are widely used in metallurgy, electric power, petroleum, chemical, air, gas, combustible gas, water supply and drainage and other corrosive media pipelines.
