Overview of Pneumatic Three Eccentric Butterfly Valve Products

The pneumatic triple eccentric butterfly valve consists of a piston type pneumatic actuator and a triple eccentric metal sealed valve body. Its structure is designed using the three-dimensional core principle, and the valve seat adopts a multi-level structure that is compatible with hard and soft seals. It is exquisitely processed and has advanced technology. The pneumatic triple eccentric butterfly valve can be equipped with an external pneumatic valve locator, which can control the operation by inputting a control signal (4-20mADC or 1-5VDC) from the air source. It can also be equipped with a travel limit switch, solenoid valve, triple piece, and 0.4-0.7MPa air source to achieve switch operation, and send two pairs of passive contact signals to indicate the valve's switch. The pneumatic triple eccentric butterfly valve consists of main components such as valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism, and is a long-life and energy-saving butterfly valve. Pneumatic triple eccentric butterfly valves are widely used in pipelines for corrosive media such as metallurgy, power, petroleum, chemical, air, gas, combustible gases, and water supply and drainage.
Main features of pneumatic triple eccentric butterfly valve

1. This valve adopts a three eccentric sealing structure, with minimal wear on the valve seat and butterfly plate.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperatures, corrosion resistance, and long service life.
3. The sealing surface of the butterfly plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life.
4. The large-diameter butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance.
5. Pneumatic triple eccentric butterfly valve has bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction.
6. The drive device can be installed in multiple stations (rotated 90 ° or 180 °) for easy user use.
