Product Overview

The oxygen butterfly valve is designed structurally such that when the valve disc opens and closes, the valve stem only rises and falls without rotating, effectively reducing the wear of the sealing pair, packing, and upper seal; The side flange is equipped with grounding screws to prevent the generation of static sparks; The exposed part of the valve stem is sealed with organic glass to prevent dust and oil.

Structural Features

Oxygen butterfly valve: 1. Adopting a three eccentric sealing structure, the valve seat and butterfly plate have almost no wear, and have a sealing function that becomes tighter and tighter as viewed 2. 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 3. 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 temperature conditions, with characteristics such as corrosion resistance and long service life.

4. The large-sized butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance 5. Metal hard sealed 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.
