Product Features:
1.Strict Oil-free Measures and Degreasing Treatment: Oxygen butterfly valves adopt strict oil-free measures during the manufacturing process, and all parts are degreased before installation to eliminate the potential impact of oil pollution on the oxygen environment and ensure safety when used in an oxygen environment.
2.Anti-static Design: The valve flange end is equipped with conductive screw holes to prevent static electricity accumulation and avoid potential dangers caused by static sparks.
3.Excellent Sealing Structure: The oxygen butterfly valve usually adopts two types of multi-layer sealing or metal sealing to ensure the tightness of the valve in the closed state, which effectively prevent oxygen leakage. Some products use the three eccentric sealing structure. The valve seat and disc are almost free of wear, with a sealing function that becomes tighter as they are closed.
4.Wear-Resistant Materials: The sealing surface of the disc is often made of welded Stellite, which is wear-resistant and has a long service life. The seal insert is made of stainless steel. It has the dual advantages of metal hard sealing and multi-layer sealing, which is corrosion-resistant and long-life.
5.Accurate Regulation: By regulate the rotation angle of the butterfly disc, the oxygen butterfly valve can achieve accurate flow regulation to meet the flow control requirements under different working conditions.
6.Low Resistance Design: The butterfly disc adopts a streamlined design to reduce fluid resistance and improve the working efficiency of the valve. When the butterfly valve is in the open position, the thickness of the butterfly disc is the main resistance when the medium flows through the valve body, therefore, there is small pressure drop generated by the valve, which has good flow control characteristics.
7.Corrosion-Resistant Materials: Valve body, disc, and other key components are usually made of stainless steel or other corrosion-resistant alloys to meet the special requirements of oxygen medium to ensure long-term stable operation of the valve under harsh working conditions.
8.Various Connection Methods: Common connection methods for oxygen butterfly valves include flange connection, wafer connection, etc., which can be selected according to the needs of the specific pipeline system.
