High Performance Butterfly Valve

The SGON High Performance Butterfly Valves are designed on the basis of absorbing the advantages of several different structural butterfly valves. The valve plate seal face of this butterfly valve is spherical arc surface body, and the sealing mechanism achieves a real dynamic seal through system pressure, so it has excellent cutting performance and durability. Its small size, light weight, wide manufacturing range, easy maintenance.

The SGON Metal Seated Butterfly Valves adopts three eccentric seal structure, the seat and butterfly plate have almost no wear and tighter sealing function. The seal ring is welded with stainless steel. It has the dual advantages of metal hard seal and elastic seal. No matter at low temperature and high temperature, it has excellent sealing performance and corrosion resistance. With long life and so on, the seal face of the butterfly plate is hardfaced with cobalt based hard alloy, the seal face is wear-resistant, and the length of the butterfly plate is long, the strength is high, the overflow area is large, the flow resistance is small, the metal hard seal butterfly valve has the function of two-way sealing, it is not restricted by the flow direction of the medium, and is not subject to the space position. It can be installed in any direction.

The Wafer Type Butterfly Valves is used to adjust the flow rate and the discharge body with precision J - shaped elastic seal ring and three eccentric multi layer metal hard seal structure, which are widely used in the gold, electric, petrochemical, water supply and municipal construction pipes of the medium temperature less than 425 degrees C. It is widely used in steam, hot water, water, oil, gas, natural gas, chemical and other process pipelines.

The SGON Cast Steel Lug Eccentric Butterfly Valves are widely used not only in petroleum, gas, chemical industry, water treatment and other general industries, but also in cooling water systems of thermal power stations. Used in the gas pipeline in the sulphuric acid industry: the inlet of the blower before the furnace, the inlet of the relay fan, the electric mist eliminator series and the connecting valve, the S02 main blower outlet, the converter regulation, the preheater exit and exit and other adjustment and cut-off air volume. The sulfur, conversion and dry sucking section used in sulphur making acid system is the first brand of the sulphur acid plant, which is considered to be a butterfly valve with good sealing performance, light operation, vice corrosion, high temperature resistance, convenient operation, flexible operation and safe and reliable use.

The SGON Welding Type Butterfly Valves is a simple regulating valve, and it can also be used for switch control of low pressure pipeline medium. Hard seal butterfly valves mainly cut off and throttling on pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate which rotates around its own axis in the valve body so as to achieve the purpose of opening or closing or regulating. The hard sealed butterfly valve is suitable for the pipes of the furnace, gas, steam, natural gas, city gas, cold and hot air, chemical smelting engineering and power generation environmental protection system to convey various corrosive and non corrosive fluid medium, which can be used to regulate and truncate the flow of the medium.
